[kwin] [Bug 408964] wayland fractinal scaling - very pixelated by default
https://bugs.kde.org/show_bug.cgi?id=408964 --- Comment #6 from Lewis Lakerink --- I can also confirm this issue. Using kscreen-doctor with 1.25x under wayland causes exactly the same pixelated fonts as your screenshots, Brian. I first encountered this issue some 12-18 months ago, and it is a show stopper for me using Plasma as I have a dell xps 4k with 2 external 4k monitors, which exceeds the maximum buffer size for the modesetting xorg driver (when scaling with xrandr). And the intel xorg driver is noticeably laggy at this resolution. Sadly, I have since moved over to using Gnome 3.32 with wayland which has been working well, but I'd still like to come back Plasma when this issue can be resolved. -- You are receiving this mail because: You are watching all bug changes.
[KScreen] [Bug 408964] Wayland fractional scaling - very pixelated by default
https://bugs.kde.org/show_bug.cgi?id=408964 --- Comment #12 from Lewis Lakerink --- I can confirm that the patch D23669.diff to force the mipmaps works very well. The fonts are no longer pixelated. I've attached a before and after, they could be less blurry, but you can clearly see that the fonts are now significantly better. -- You are receiving this mail because: You are watching all bug changes.

[kwin] [Bug 426293] All my Qt clients die when I disconnect my display
https://bugs.kde.org/show_bug.cgi?id=426293 Lewis Lakerink changed: What|Removed |Added CC||le...@retsim.com --- Comment #5 from Lewis Lakerink --- I came here to say that this issue hits me too. I searched up this issue recently, but somehow missed this report or I'd have gotten involved sooner. Docking my laptop works as expected, extra screens are added just fine. But as soon as I undock, all the Qt applications crash. The debugging I did arrived at the same conclusion as Vlad, but I don't have enough knowledge of wayland to help with this bug. I'm using Gentoo live ebuilds for plasma, so I have not reported this issue due to this. Happy to help in any way I can however. -- You are receiving this mail because: You are watching all bug changes.
[kwin] [Bug 426293] All my Qt clients die when I disconnect my display
https://bugs.kde.org/show_bug.cgi?id=426293 --- Comment #8 from Lewis Lakerink --- Just to double check, MR!98 is for a version of Qt (5.15.3) that isn't even on the Qt release schedule yet? I have the latest stable Qt release, QT 5.15.1 installed, and this patch is just a noop for that version. I tried changing the version check in your diff to 5.15.1, but kwin just crashes when removing a monitor. I'm super keen to try out this diff, and I'm happy to upgrade to an unstable Qt to do so if required, but wanted to check. Does that mean this bug could take a while to land a fix for since we'll be waiting for upstream Qt?

https://bugs.kde.org/show_bug.cgi?id=426293 --- Comment #10 from Lewis Lakerink --- (In reply to Vlad Zahorodnii from comment #9) > No, I screwed the pooch with Qt versions. It's 5.15.2 All good. I rebuilt the relevant parts of Qt 5.15.1 with your patches from qtwayland. - https://code.qt.io/cgit/qt/qtwayland.git/commit/?id=c594b7622f52dea291d33757b74971b3902b5d37 - https://code.qt.io/cgit/qt/qtwayland.git/commit/?id=4a4c35a856cf64f0e165cc3cfaeb1a3bbbf471f6 Then applied your MR!98 - changing the version check to 5.15.1 and rebuilt kwayland-server and relevant plasma bits. I am able to confirm that unplugging my dock no longer kills the Qt clients. I've tried a variety of screen configurations and adding/removing displays via my dock works perfectly. Nice work!

https://bugs.kde.org/show_bug.cgi?id=438097 --- Comment #5 from Lewis Lakerink --- Annoyingly, I'm still seeing weird behaviour after time with xwayland and sometimes kwin crashing and restarting the session - however, I no longer get coredumps for kwin, and I've no idea why that is. The only evidence I have that a segfault occurred is in dmesg. I've set a huge max size on my core dumps, so no processes should be excluded from dumping, I'm not sure what else to do. -- You are receiving this mail because: You are watching all bug changes.

[plasmashell] [Bug 438381] New: plasmashell crashes occasionally when the dock hides/shows
https://bugs.kde.org/show_bug.cgi?id=438381 Bug ID: 438381 Summary: plasmashell crashes occasionally when the dock hides/shows Product: plasmashell Version: 5.22.0 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: crash Priority: NOR Component: generic-crash Assignee: plasma-b...@kde.org Reporter: le...@retsim.com Target Milestone: 1.0 SUMMARY Sometimes plasmashell will crash after a while when either trying to hide or show the dock. I have my plasmashell dock (Not latte, just the standard dock shipped with plasma) on the right side of my monitor. It often works perfectly for a few hours, but then after some time plasmashell terminates (not a segfault). Usually I don't notice it's crashed until after I try to show the dock with my cursor, and it no longer opens. The crash can happen after 10 minutes, other times it happens after several hours. STEPS TO REPRODUCE 1. Run plasmashell (Or use plasmashell that's launched at login) 2. After some time of using the desktop, plasmashell will terminate. 3. If I'm lucky enough to have a terminal open (Usually I do), I can relaunch plasmashell, but it too will crash after some time. Plasmashell works fine initially after launching it again. Task thumbnails are fine, everything is functional until it's next random crash.

[kwin] [Bug 438097] New: [AnimationEffect] kwin_wayland sometimes crashes when right clicking in an xwayland program
https://bugs.kde.org/show_bug.cgi?id=438097 Bug ID: 438097 Summary: [AnimationEffect] kwin_wayland sometimes crashes when right clicking in an xwayland program Product: kwin Version: git master Platform: Compiled Sources OS: Linux Status: REPORTED Severity: crash Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: le...@retsim.com Target Milestone: --- SUMMARY (I assume) Some kind of internal effects change causes animations to be added with a null EffectWindow* key in m_animations. I've also observed crashes in AnimationEffect::paintWindow() - however I don't have a stack trace or line number for this, as I was using the ArchLinux 5.21.90 packages without debug info. STEPS TO REPRODUCE 1. Use an xwayland jetbrains IDE for some time 2. Eventually right clicking the source code to bring up the context menu will crash kwin 3.

[kwin] [Bug 438097] [AnimationEffect] kwin_wayland sometimes crashes when right clicking in an xwayland program
https://bugs.kde.org/show_bug.cgi?id=438097 --- Comment #2 from Lewis Lakerink --- I'm not sure if it's related - but sometimes kwin_wayland won't crash - but instead all my xwayland clients die (I guess xwayland itself crashes), and I'm not able to start an xwayland client again without logging out of my session and back in. Perhaps if the xwayland server crashes midway through a render xwayland related animations lose their EffectWindow? I don't know how that works internally, I'm merely speculating - and xwayland dying may be unrelated to this ticket. -- You are receiving this mail because: You are watching all bug changes.

[kwin] [Bug 441400] New: [Wayland] Screen edges don't appear to be correct for multi-monitor layouts
https://bugs.kde.org/show_bug.cgi?id=441400 Bug ID: 441400 Summary: [Wayland] Screen edges don't appear to be correct for multi-monitor layouts Product: kwin Version: git master Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: le...@retsim.com Target Milestone: --- Created attachment 140962 --> https://bugs.kde.org/attachment.cgi?id=140962=edit Display configuration SUMMARY Using the wayland session, with the (see attached) monitor layout, screen edges seem completely broken. 1. The standard screen edge highlight desktop effect does not work on any monitor. 2. My panel (on the right of my Laptop Screen) is set to autohide, in the attached screen layout, the panel never hides. When I mouse to the edge of the Laptop Screen and move the cursor off the panel it will hide the panel and immediately show it again as if the screen edge is instantly retriggered (I can provide a video of this behaviour if required). 3. If I disconnect my extra monitors (undock) the screen edge desktop effect on my Laptop Screen starts working correctly again, as does the autohide of the panel. I have not tested different layout configurations to check if it's just an issue with that specific display configuration. STEPS TO REPRODUCE 1. Use a plasma wayland session 2. Configure the displays as in the attached display config. OBSERVED RESULT Panel autohide and right hand side screen edge highlight stop working when using multiple displays. EXPECTED RESULT Panel should autohide as expected and the screen edge highlight should work.

[kwin] [Bug 438097] [AnimationEffect] kwin_wayland sometimes crashes when xwayland tries to display a popup

Exactly the same symptoms for me with Pycharm and CLion. After some time (sometimes half an hour, sometimes several hours) triggering the intellisense popup will eventually trigger this error. I haven't seen this crash with any other xwayland applications however. I've been running kwin master (updated once or twice a week) more or less since I reported this bug, however since 5.22.90 was tagged I've changed to Plasma/5.23.

https://bugs.kde.org/show_bug.cgi?id=438097 --- Comment #26 from Lewis Lakerink --- Firstly can I just say Ash, thanks for your in depth analysis! It's been super educational for me to see your process and how you use GDB to debug the issue. Nice find with the fds, I can confirm that that is the same for me. Watching the fd count while opening/closing popups in pycharm shows that fds are increasing until they reach ~the soft limit of 1024 on my system before plasma goes crazy/kwin crashes. I've just set the soft/hard fd limit to a million and will see if that prevents pycharm/clion crashing kwin as regularly. I'll post my findings after some testing. (Less than ideal workaround for sure, but if that temporarily resolves this problem until it can be fixed - I can live with that!) > wl_display@1: error 1: invalid arguments for > zwp_linux_buffer_params...@30.add > [266 00:35:18.863341] [glfw error 65544]: Wayland: fatal display error: > Invalid argument Looks exactly like the same symptoms I had for https://bugs.kde.org/show_bug.cgi?id=438381, so I'd go so far as to say that issue is related to this issue. -- You are receiving this mail because: You are watching all bug changes.
[kwin] [Bug 438097] [AnimationEffect] kwin_wayland sometimes crashes when xwayland tries to display a popup
https://bugs.kde.org/show_bug.cgi?id=438097 --- Comment #28 from Lewis Lakerink --- Ok, so setting the hard/soft fd limit to a high value appears to be an effective solution for me for now until this issue is resolved. Using Ash's xdotool script modified for pycharm, I got the kwin fd count up over 50,000 (took ~35 minutes) and no kwin crash, plasmashell is also still working fine before I stopped the xdotool script. I measured the fd's open by kwin using watch -n 1 "sudo ls -la /proc/`pidof kwin_wayland`/fd | wc -l" $ ulimit -Sn 1048576 $ ulimit -Hn 1048576 $ sudo ls -la /proc/`pidof kwin_wayland`/fd | wc -l 50074 For posterity sake, I changed my limits by editing /etc/security/limits.conf and adding the following lines to the end and rebooting. lewis softnofile 1048576 lewis hardnofile 1048576 -- You are receiving this mail because: You are watching all bug changes.
