After last(Or one before last) update, I see strange behavior in my screen.
I considered that KWin
is unable to render transparent windows correctly.
A sample situation is as below:
- I located
Cairo-Duck
on right side of my screen. NOTE: I think Cairo-Duck uses OpenGL but Iβm not sure. - I use a transparent background for
Konsole
which is my typical terminal. - When Cairo-Duck appears, it causes screen to tear on left side.
To make it more clear, I recorded a sample video from this problem:
A recorded GIF of problem
A recorded MKV video of problem
As you can see, when Cairo-Duck
is hide, everything is good but when it appears the color of terminal on left side changes frequently. If you need a better Video-Record from problem, feel free to tell me.
Itβs really annoying me and any help or suggestion is appreciated
NOTE1: This problem is not limited to Cairo-Duck
. Some other applications such as xsnow
, oneko
and β¦ causes this problem too and thatβs why itβs annoying to me!
Also when I right click in Visual Studio Code
, I see this problem again exactly around opened window or pop-up.
But this problem just happens in case of transparent windows and borders
NOTE2: I didnβt have this problem before! This problem is caused by last update or one before last updateβ¦ Iβm not sure which one caused this.
My Suggestion:
I think this problem is related to OpenGL
but backend rendering
option is missed in system settings and I canβt make sure if this problem is related to OpenGL or not:

- Clearing the Plasma Cache didnβt help
