[Bug 1893969] Re: Screen corruption and delayed update using onboard Intel video
It happens for sure in the following applications (which I think rules out the application and toolkit, but not the compositor or Xorg): * Firefox * Emacs * Electron apps (Keybase, Slack, Element) * Okular * OBS (maybe; this may be a different problem) * FreeCAD (maybe; FreeCAD has painting problems in general) * VMware (both the UI and the guest) Interestingly, I don't think I have seen any misbehavior in urxvt, which I use a lot. I am not using GNOME. My window manager is awesome and my compositor is compton. The mutter package is not installed on this machine. I will try to get more screen shots, although this is hard to capture because disturbing the window often causes a repaint. I have tried to capture video a few times, but as I am working with private information that does not belong to me on this machine I haven't yet captured an instance where there was nothing on my screen I am unable to share. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893969 Title: Screen corruption and delayed update using onboard Intel video To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1893969/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for the screenshot. It's hard to tell if that's a bug in the application, the toolkit, Xorg or the compositor. Please continue collecting more screenshots of the problem. Please also try a different desktop environment that's not GNOME. If your xrandr command triggers the same problem without GNOME then we don't need to involve the 'mutter' package in this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893969 Title: Screen corruption and delayed update using onboard Intel video To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1893969/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1893969] Re: Screen corruption and delayed update using onboard Intel video
The specific part of the screen shot with obvious corruption is cropped below. I'll try to get a video; one problem I have is that many of the specific things I do that reliably show the problem are at times when private data is visible on my screen. I _cannot_ show this problem without the XrandR command (or some GUI- configured equivalent), because it seems to only happen with external DisplayPort monitors attached. When I use _only_ the internal laptop panel things appear to work correctly (or did last time I checked, I very seldom run only one display). I believe the problem is triggered by either 1) daisy-chained DisplayPort monitors or 2) the sheer size of my desktop (11520x2160). I will try to find something that reliably corrupts that is not sensitive to get a video, and I will test with no external displays attached and verify that that is still error-free. ** Attachment added: "corruption.png" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1893969/+attachment/5412195/+files/corruption.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893969 Title: Screen corruption and delayed update using onboard Intel video To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1893969/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1893969] Re: Screen corruption and delayed update using onboard Intel video
I can't see a problem in that screenshot or the logs. Maybe consider attaching a video instead? Also please tell us if the problem happens: * Without your custom xrandr commands * In a Wayland session (select 'Ubuntu on Wayland') from the login screen after selecting your username. ** Tags added: xrandr-scaling ** Tags added: multimonitor ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New ** Changed in: mutter (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893969 Title: Screen corruption and delayed update using onboard Intel video To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1893969/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
