SUMMARY Please see the video: https://youtu.be/zikzg5cDIrs This is with xorg, mesa with amd gpu The two major things are: 1) spectacle's "rectangular region" mode is shifted to the left, and I can't screenshot the left part of the desktop 2) yakuake doesn't show up on a monitor, or, with two monitors, it shows but with a smaller / wrong width This seems to also glitch part of some applications, for example QtCreator works "better" on the left monitor, on the rightmost one it tends to glitch and not update the screen / render some panels with wrong size STEPS TO REPRODUCE 1. attach more than one monitor (tested with 2 and 3 4k monitors) 2. admire the breakage I can reproduce this with another clean user, so it shouldn't be a configuration issue OBSERVED RESULT Bugs EXPECTED RESULT The absence of bugs SOFTWARE/OS VERSIONS Latest version of everything in Arch Linux, this has been going on for ages ADDITIONAL INFORMATION $ xrandr --listmonitors Monitors: 3 0: +*DisplayPort-1 3840/600x2160/340+3840+0 DisplayPort-1 1: +DisplayPort-0 3840/607x2160/345+7680+0 DisplayPort-0 2: +HDMI-A-1 3840/608x2160/345+0+0 HDMI-A-1
Can you take screenshot of all screens when kwin is broken? Does it look good?
Use this command qdbus org.kde.KWin /Screenshot screenshotFullscreen
The screenshot "Full Screen (All Monitors)" in spectacle looks good, so does the qdbus command you gave me, it's not broken Regarding the screenshots issue, it's just the "preview" thing inside spectacle that is shifted, and I can't reach the leftmost part because it's "outside" the monitors
Can you reproduce this bug when full screen repaints are forced? In order to force full screen repaints, go to compositor setting and choose "Full screen repaints" swap(tearing prevention) strategy.
s/setting/settings/
I can reproduce the bug with "Full Screen Repaints" enabled
Can you reproduce the bug when compositing is suspended? (press Alt+Shift+F12 to toggle compositing)
Yes I can, both "symptoms" persist with compositing disabled
Please post xprop output of the panel when "kwin" is broken.
and also output of qdbus org.kde.KWin /KWin supportInformation

"kwin" is always broken since I can't open yakuake in the rightmost monitor, the problem is persistent Is the issue with the panel and not with kwin? I'm confused on what does what
