Description Andreas Nordal 2024-05-17 17:58:15 UTC

Application: kate (24.02.2)

Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.8.8-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
I like that you can maximize or half-size a window by dragging it over the top or side edges.
This was no problem in KDE5, but in KDE6, it sometimes crashes the window.
Kate is no special. It happens to Konsole and Firefox too.
When it's firefox, the whole desktop crashes and /dev/null becomes replaced with a regular file
(usually of zero bytes, but sometimes containing a linefeed terminated message),
and KDE hangs forever when I try to restart it, so I have to reboot.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault

kate (24.02.2) using Qt 5.15.13

Exactly the same happened again.
I dragged Kate to the right half side of the screen.
It's usually not that often.

kate (24.02.2) using Qt 5.15.13

Third time in a row. I think I'm discovering a more consistent way to trigger it. I accidentally made the window quarter-screen-sized before I hit the point where it becomes half-sized.

Comment 3 Waqar Ahmed 2024-05-18 13:43:52 UTC

Your version information is incorrect. Qt version can't be Qt5 and Frameworks can't 5.X. 

Anyways, it doesn't matter much.

Can reproduce the issue, trying to tile Konsole on top right corner for e.g., leads to freezes and hangs.

Comment 4 Waqar Ahmed 2024-05-18 13:47:42 UTC

can't reproduce it always.

moving to kwin

Comment 5 Andreas Nordal 2024-05-28 22:57:10 UTC

That version info I think was filled in by DrKonqui (I don't remember writing it).

It happened again. Here is what happened to poor /dev/null when when it was Firefox I resized, so that KDE6 crashed and can't be restarted:

> ls -l /dev/null 
-rw------- 1 root root 9 mai   29 00:47 /dev/null
> sudo xxd devnull

Comment 6 Vlad Zahorodnii 2024-10-01 09:51:34 UTC

Does the crash happen in Plasma 6.1?
