Bug ID: 466369
Summary: Third party aurorate titlebars don't update graphics
correctly when resized under new tiling in Wayland
Classification: Plasma
Product: kwin
Version: 5.27.1
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: aurorae

Tiled-Gwenview
SUMMARY
***
When I tried out the new tiling in Plasma 5.27, I noticed that some (not all)
apps get completely distorted titlebar graphics, sometimes during a tiling,
sometimes after coming out of the tiling mode. This was noticed under Wayland.
***
STEPS TO REPRODUCE + OBSERVED RESULT
1. Log in into Wayland session
2. Have third party aurorae theme, like WhiteSur-dark
3. Apply new tiling (shift+drag window), resize the titled windows, then drag
the window out of tiling. Some apps (didn't find a rule yet), like for example
Gwenview, get completely distorted titlebar graphics - see the attached
screenshot.
EXPECTED RESULT
Third party titlebars should maintain properly updated graphics during and
after tiling.

ADDITIONAL INFORMATION
I am still finding a rule, but so far it looks like a random occurrence. Once I
saw it with Thunderbird, then I couldn't repeat it. Then I saw it under
Dolphin, then I couldn't repeat it. Now, I caught this bug on Gwenview and made
the screenshot.
Sometimes the problem is visible during a tiling, and then it's fixed when the
app is out of tiling mode. Sometimes the bug stays.
Weirdly, when the graphics returns to normal out of tiling, when the app is
tiled, the same visual bug appears right away, as if it was remembered.
During the writing this bug description, I couldn't repeat it on Dolphin, but
then I tried again, and the bug came again and is repeatable. When the window
is widened above half of the screen, the titlebar is widened horizontally. When
the window is below the half of the screen, the titlebar is shortened beyond
the windows width and the titlebar graphics is distorted.
I haven't tested it under X11, so I don't know if the bug happens there as
well, but I suspect it may be a Wayland thing.
