Greyed-Dolphin-Titlebar-After-Unsuspend-0

NOTE: See *Update:* section below in this report for updated and current workaround implemented here. 

Initial Problem:

I have a fully updated 64 bit openSUSE Tumbleweed installed. Even before the latest snapshot this was happening. I notice that after suspend/unsuspend the preexisting titlebars (Dolphin instance, KeepassXC instance and Firefox instances etc. That the titlebar color has turned to greyed state (on all the open preexisting application windows) with the specific applications Titlebar information being nearly illegible (slightly more greyed than the rest of the titlebar). 

Currently the system here is set for Global Theme openSUSE, Application Style is set to Breeze, Plasma style is set to openSUSE Follows color scheme. Colors are set to Breeze Classic and Window Decorations are set to Plastik. These settings are confirmed (static) and have been applied for some time between powercycles.

Newly opened windows (after unsuspending *OR* freshly booted) open with a fully legible and colored titlebar, labeled with easy to read location indicator on the upper left of the titlebar. I have attached a snapshot of an afflicted Dolphin instance to this message.




If this is not a bug how can I fix this problem? Do you think this could be related to the actual Nvidia driver itself? Or possibly the video card?


Update:

After unsuspending the system and experiencing the issue. System Settings -> Window Decorations -> Select 'breeze' apply settings. <- Colors reappear. Changing application window size (middle button, far right of titlebar) no longer causes characacter size to change either.
Switching back to Plastik works fine. Until next suspend/unsuspend cycle is performed. 

Using *only* the Breeze window decoration does not appear to have this issue at all.   

STEPS TO REPRODUCE
1. Suspend then Unsuspend the machine. Sleep/Unsleep machine into onboard memory.
 

OBSERVED RESULT
Greyed out and almost illegible window titlebar display information.

EXPECTED RESULT
Legible and colored window titlebars. Able to change size without crashing the window when attempting to resize.

SOFTWARE/OS VERSIONS
Linux: openSUSE Tumbleweed
KDE Plasma Version:  5.27.10
KDE Frameworks version = 5.115.0 
Kernel Version = 6.7.7-1-default (64-bit)
Graphics Platform = X11
Qt Version: 5.15.12

ADDITIONAL INFORMATION
For now the workaround is to *USE* only the (available by default) Breeze window decorations as the Plastik window decorations seem to be very problematic.

Corrupted-Window-Titlebar-Once-Resized

Added a screenshot of the titlebar description becoming corrupted when resize (top right middle button) is attempted. Attempting to maximize (click again) then crashes the window.
Comment 2 panorain 2024-03-08 04:21:25 UTC 
If I pass 'journalctl -f' in Konsole. Suspend and unsuspend the machine with the Plastik window decorations and view the Konsole output is:

Comment 3 Nate Graham 2024-03-10 04:55:35 UTC 
Is it happening on Plasma 6 too?
Comment 4 panorain 2024-03-10 05:48:22 UTC 
openSUSE Tumbleweed has not released a Plasma 6 package yet (in zypper dup). It's in staging and people are talking about it on the factory mailing list. It's available in the oss build repository I think. Who develops the Plastik window decorations anyways?
