Description Mihaela 2020-02-26 03:58:09 UTC

Application: kwin_x11 (5.16.5)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-40-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:

This happens almost always: I close a window and he Fall Apart animation happens. This animation isn't so short (any way I can change that time BTW?). I then change to a different desktop/workspace which triggers the Cube animation. 

If I do that while the shards of the closed window animation are still happening KWin crashes, or there some weird things happening with the windows on the next desktop, flickering or it takes a moment until the display is rendered. Sometimes the current desktop image is frozen for a bit, including the shards it all stands still before it moves to the new desktop. Sometimes the new desktop is not the next one, but the second one, probably because the mouse keep pushing in that direction. 

- Custom settings of the application:

Enabled Fall Apart, Desktop Cube and Desktop Cube Animation under Desktop Effects. 

In the Animation: 
Do not animate panels
Use pager layout for animation

Under Virtual Desktops I have 5 rows, each with 1 Desktop
Show animation when switching: Desktop Cube Animation
Show on-screen display when switching: 500 ms
Show desktop layout indicators

The crash can be reproduced sometimes.

Addendum: 

KWin won't start again, even after shut down. 

Here is some more info about my config and the commands I used to try to start it:

This is possibly a duplicate of https://bugs.kde.org/show_bug.cgi?id=368847#c5 (Assert in KWin::WindowQuad KWin::WindowQuad::makeSubQuad)

When I try `kwin --replace` in terminal I see these messages after closing a window:

Moving a window from one desktop to the next by holding and dragging:

There are no messages if Desktop switching animation (under Virtual Desktops) options aren't turned on. 

But if I turn on "Show on-screen display when switching":

If I turn off the "Show on-screen display when switching":

If I also add "Show desktop layout indicators":

Go to the compositor settings (system settings > display and monitor, compositor) and re-enable compositing.

According to the title, yes.

Comment 6 Mihaela 2020-03-02 13:52:55 UTC

Thank you @Vlad for the tip on how to get Compositor working again. 

Why wouldn't it work with the terminal, or better yet, through Run?
