systemsettings 5.8.4 freezes when resized

systemsettings freezes when in one of:
- "Workspace Theme" > "Look and Feel"
- "Workspace Theme" > "Desktop Theme"
- "Workspace Theme" > "Splash Screen"
and the window is resized.

The system is running Xorg 1.19.0 with the nouveau driver (please see system details below). It was previously running a older version of Plasma and Xorg with the nvidia driver. I don't remember seeing this bug then so it may be a regression in Plasma, an issue with the newer Xorg or with the nouveau driver.



Reproducible:

Always.



Steps to reproduce (please see attached video):

1 - Run systemsettings version 5.8.4 (may occur in other versions);
2 - Select "Workspace Theme";
3 - Select "Look and Feel", "Desktop Theme" or "Splash Screen";
4 - Resize window for a few seconds (may not freeze at first resize, retry a few times);

After triggering this bug, I tried switching to another virtual console and then back, as mentioned in https://bugs.mageia.org/show_bug.cgi?id=19869, and it does unfreeze the systemsettings.

Comment 3 Tony 2016-12-07 11:51:57 UTC

Can't reproduce on neon unstable+NVIDIA-375 drivers.

Comment 4 Kai Uwe Broulik 2018-07-20 12:56:36 UTC

Is this still an issue with the redesigned KCMs shipped in Plasma 5.13?

Comment 5 PC LX 2018-07-21 08:53:14 UTC

I'm currently using Plasma 5.12.2 and can't reproduce the issue. Seems this issue has been solved.

$ systemsettings5 --version
systemsettings 5.12.2
$ rpm -qf $(which systemsettings5)
systemsettings-5.12.2-1.mga6
