[kwin] [Bug 459373] Maximized XWayland apps leave some pixels on the right border with fractional scale factor
https://bugs.kde.org/show_bug.cgi?id=459373 --- Comment #25 from Hexagon --- Hi guys. I would highly recommend to add this issue to the "15 minute bug initiative" https://tinyurl.com/plasma-15-minute-bugs. I am using Plasma (Wayland) with these pixel bugs now for several months and it is not fixed at all, contrary to some comments here. Only on some configurations of monitor placement, resolutions and (important!) scaling the border disappears. But one should not have to worry to set the scaling smaller or bigger than wanted, just to prevent this ugly visual problem, which makes Plasma look buggy from the very first minute of usage where you configure your screens. Also it is a major selling point of Wayland, that now scaling works correctly, important for newer Hi-DPI monitors. This would contradict, at least for KDE Plasma. Unfortunately I am not a C++ developer myself to provide a fix myself, but I can provide testing data. Here are my findings: - I am testing with the program glxgears which provides a black background and runs in Xwayland. Then I set my desktop background to full white. That way one can see the pixel rows better. - I am using a triple monitor setup with (from left to right): A: 2560x1440@150%, B: 3840x2160@200%, C: 2560x1440@150% - I am using the newest release plasma-wayland-session 5.27.1-1 on Arch - By chaning the scaling of the monitors A, B and C I can produce three different states on all of them: 1) No borders at all (perfect) 2) Vertical pixel row on the right spanning up even to the header bar of the window with the size of 1 pixel 3) Number 2 + Horizontal pixel row on the bottom with the size of 1 or 2 pixels Thanks for your work in this. I hope we can get a real fix soon to make the pixel border a thing of the past, regardless of monitor placement, resolutions and scaling settings. If you need more information don't hesitate to ask. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=459373 --- Comment #24 from André M --- The situation seems to have improved on Plasma 5.26.90 (5.27 beta): While moving a *xwayland window* between 2 monitors (main 2560x1600 150% with left, top panels; right 2560x1440 135% no panels), when they go to the other monitor while already maximized, they occupy the correct area on the other monitor, leaving no gaps; when unmaximizing and re-maximizing in place, the right border still leaves a couple of pixels off, showing the wallpaper or window below, as before. Either way, bottom gap is gone. -- You are receiving this mail because: You are watching all bug changes.

It is also noticeable in VLC. In Blender, most of the app looks very crisp and nice thanks to using its own scaling, but near the right side and bottom, elements are slightly blurry.
