Description Kamil Piwowarski 2018-07-01 15:32:22 UTC
Using latest Manjaro with Plasma 5.13.2

Steps:

1. Run Konsole with blur background enabled on wayland session. 
2. On first monitor it looks ok, but on next screens there are random glitches.
3. Test again on X session - it works perfectly.

Kate and Dolphin behind Konsole

Do normal windows look okay behind Konsole? (like on the attached screenshot)

kwin_wayland without plasma

I was doing some testing and experiments and when I run kwin_wayland remotely by ssh `XDG_SESSION_ID=c2 QT_QPA_PLATFORM=wayland kwin_wayland --libinput --exit-with-session=konsole` it almost works as expected. Almost, because you can see "lines" between screens.

wayland - vertically aligned to the top

Another bug - on vertically stacked screens (aligned to the top). See screenshot.

aligned to the left

Only bottom monitor is ok
Comment 12 Vlad Zahorodnii 2018-07-01 21:24:21 UTC
I think this bug is caused by

const int yTranslate = effects->virtualScreenSize().height() - screen.height() - screen.y();

it essentially "pulls" screen content down. Still, I'm not sure why this bug is not reproducible when launching windowed kwin_wayland.

Interesting.

Comment 14 Kamil Piwowarski 2018-07-01 23:18:48 UTC
I am so stupid ;/ Sorry for wasting your time. Everything is ok.

Some months ago I've testing multiscreen setup and I've created backup of `/usr/lib64/libkwin4_effect_builtins.so.1` --> `/usr/lib64/libkwin4_effect_builtins.so.1.bak`. When testing I've changed symlink from `/usr/lib64/libkwin4_effect_builtins.so.1.0.0` to point `/usr/lib64/libkwin4_effect_builtins.so.1.bak`. During updates symlinks didn't changed. So I was using old file libkwin4_effect_builtins.so and that was a problem.
