Bug 429982

SUMMARY

Sometimes (trigger is unknown) gtk configs are not updated and stay in some weird, incorrect state. This has two effects:

1. When setting a new GTK theme, all seems to work fine.
2. After session relog, we get some bizarre, broken window buttons on apps with client side decoration, like Pamac.


There are no steps to reproduce because I can't trigger it at will, but it happened to me twice since the last Plasma 5.20 update, which forced me to delete:

~/.config/gtk-3.0/

I also noticed, that there were at least 4 or five similar issue topics on Manjaro forums, so this is happening all the time on various systems. Because it is only visible when messing with GTK themes and aurorae themes and on client side decorations, it's easy to miss this issue.



EXPECTED RESULT

Window buttons drawn from currently set GTK theme.

Operating System: Manjaro Linux
KDE Plasma Version: 5.20.4
KDE Frameworks Version: 5.76.0
Qt Version: 5.15.2

OS Type: 64-bit
Processors: 8 × Intel® Core™ i7-6700HQ CPU @ 2.60GHz
Memory: 7.6 GiB of RAM

ADDITIONAL INFORMATION

I'm sending packed corrupted configs, plus the default one on which it works fine. - > Wait, Ark is not working for me at the moment, no loaded library... Not sure what happened. I upload the packed configs when I fix the package issue.

In meanwhile, see the threads on the Manjaro forum, where you have screenshots of the ill effects of that bug.

This seems to be a known bug that is causing a lot of confusion and frustration for the users.
