Hi, I've been sent here from the kde bug tracker, here's the original issue with all the info https://bugs.kde.org/show_bug.cgi?id=411652
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
some times if I move a windows in the rightmost monitor, the cursor teleports to the left one while the windows remains on the right
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
ArchLinux with everything up to date and RX480
Please attach your dmesg output and xorg log (if using X). Does it work properly with a bare xserver? Does it work properly if the desktop is less wide (e.g., running all monitors in a lower res)?
Thanks for the reply
I disabled one screen and ran the other two in 1080p and the yakuake problem persists
I then tried openbox but was unable to test for the bug, as spectacle and yakuake did not work in that environment.
The bug persists with the compositor disabled inside kde.
With gnome, spectacle works fine, and I'm unable to test for yakuake.
Do you know of a better tool I can use to debug this? The malfunction of the kde apps seems to be just a symptom of the underlying problem

Does this also happen with the modesetting driver instead of xf86-video-amdgpu?
Please also attach the output of
But TBH, it's hard to imagine how this could be caused by a driver issue. The drivers don't have any direct influence on if/where/how windows are created or displayed. This looks like an issue between kwin and the applications.
