[Bug 1870736] Re: [nvidia] Screen scaling 125% gives 200%
@optonox, I think you will not get a satisfactory answer to your questions. The issues that manifest this behaviour, as I understand it, are sprawling. The implementation of highDPI on the platform is quite naive, and fragmented due to the various packages handling the rendering, and the various UI libraries used to create the apps. That's before we get to driver vendors etc. I'm just a user, and image processing/computer graphics is my full time job - I wouldn't know where to start contributing. It is going to be a long, long road to a decent experience for High DPI screens and multiple DPI setups. That's my very unhelpful 2 pennies worth, hope it helps. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1870736 Title: [nvidia] Screen scaling 125% gives 200% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1870736/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 1558768] Re: gvfsd-trash causing high CPU-load when try to empty trash with thousands of files
I am on Ubuntu 20.04 with 64GB RAM and Threadripper 32 Core, when emptying trash, with 32K files (the Flikr 30K dataset), a number of gvfsd-trash threads are spawned and the Gnome desktop freezes. To determine it was gvfsd-trash, I switched to another tty, logged in to console, and killed the process using htop. This restored desktop functionality. I don't know what to look for in the logs, but I can reliably reproduce the behaviour. Steps: 1. download the flickr 30K dataset : https://www.kaggle.com/hsankesara/flickr-image-dataset 2. Extract and then open the folder containing the files (this will take about 22s in Nautilus on my workstation, as an aside this operation takes >2s in Windows Explorer), 3. Select All (This takes about 9 seconds, as an aside, this operation takes >.5 seconds in Windows Explorer). 4. Delete files (This takes a few minutes) 5. Empty trash and watch Gnome Shell and all applications hang like me?? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1558768 Title: gvfsd-trash causing high CPU-load when try to empty trash with thousands of files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1558768/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 1870736] Re: [nvidia] Screen scaling 125% gives 200%
@mobilebackup - agreed that there are going to be lots of problems this workaround will not solve. It is not yet clear whether any 'weirdness' is caused by the original bug or the workaround. With regards to the title bar, I am using the default gnome theme, with 'Larger Text' enabled in universal access. This seems to work with most applications; however, in CLion and other Jetbrains IDE's im having to set the font size to 48 to make it readable, as it does its own rendering. Are you using a theme that renders its fonts for example? or are you using a default theme? Also, what other wierdness are you experiencing - I am getting lagginess and jittering - however this is mostly when changing large amounts of the screen (hense the comment about large rendering areas). Sorry I'm not of more help, I would like to be, but the rendering stack is a monolith - I was commenting on past experience of rendering larger areas and scaling down (it doesn't work very well); that said, I can currently do work on my configuration. Apologies for more ramblings, if they are not helpful. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1870736 Title: [nvidia] Screen scaling 125% gives 200% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1870736/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1870736] Re: [nvidia] Screen scaling 125% gives 200%
The problems you are experiencing @mobilebackup and @agwin, are most likely due to the way the workaround works. Correct me if I am wrong, but the workaround is asking the graphics system to render a larger canvas (say 2x, 8K or whatever) and scales this down to the viewport size. If an application is not enabled for HiDPI mode, they will be very squished. If you don't have sqaure pixels (like most of us), you will get bad text, and if you don't check for orientation, the viewport will break. The reason I said this is a fab workaround, but won't hold for production, apart from above, is we are asking the card to render a huge area. If you move windows around or watch video with GPU decoding, the card is going to have to move a huge amount of data around. These are my ramblings, for whatever they are worth. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1870736 Title: [nvidia] Screen scaling 125% gives 200% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1870736/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1870736] Re: [nvidia] Screen scaling 125% gives 200%
@TreviƱo Your ppa work for me in terms of proportional, fractional scaling to 125%. My configuration is Ubuntu 20.04 x86_64 GeForce GTX 1060 440 tested driver Log attached - Thank you for your work on this. Text aliasing is not correct, there is some sub-pixel bulging that appears like a larger texture area is being rendered and scaled down incorrectly (perhaps bilinear scaling down to the output resolution). If this is the case, it is a good workaround, but not suitable for professional workflows. If we know roughly what the issue is, I am happy to test/look at code etc. Re: my comment about this not getting past test. If the testers are using a different driver set, then to say the (prop) drivers are tested is not really representative; I know a lot of people are donating their time, and I know we can't test all the configurations - but this is core functionality. ** Attachment added: "log as requested" https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1870736/+attachment/5387903/+files/log.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1870736 Title: [nvidia] Screen scaling 125% gives 200% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1870736/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
