Comment 2 Nate Graham 2020-11-13 18:55:41 UTC 
can you run:

rm ~/.cache/plasma*

plasmashell --replace

and see if that fixes it?
Comment 3 Patrick Silva 2020-11-14 12:46:17 UTC 
I reinstalled my system 2 days ago and the previous installation had the same bug,
then I don't think that this bug is related to cache. But I will follow your instructions when
the bug to occur again.
Comment 4 Patrick Silva 2020-11-20 11:54:52 UTC 
The bug is less noticeable after your commands.
However, after re-login I get exactly the same result shown in my screenshot.

Comment 10 Nate Graham 2021-03-20 02:52:53 UTC 
Are you using a scale factor of any sort and switching between the Wayland and X11 sessions? If so I suspect you're hitting Bug 396791. I am, and I can sort of reproduce this bug sometimes.
Comment 11 Patrick Silva 2021-03-20 11:33:43 UTC 
I use display scale 100%.
I can reproduce switching between X11 and Wayland sessions.
Comment 12 Nate Graham 2021-03-20 15:27:14 UTC 
OK, if you're not changing the scale between Wayland and X11, then it's probably not that exact issue. Perhaps something related though.

This bug gets worse with third-party Plasma style.
The attached screenshot shows Layan Plasma style on neon unstable.
Comment 14 Nate Graham 2021-06-14 19:33:02 UTC 
Cannot reproduce anymore with current git master. Is anyone else able to reproduce?
Comment 15 Patrick Silva 2021-06-15 02:56:03 UTC 
bug persists on my neon unstable.

Notification corners have white pixels

I have a slightly different issue but maybe they are related. When I use Breeze Dark theme, switching from Wayland to X, I see white artifacts around the corners of popups and notifications.

reported as bug 438644
Comment 20 Nate Graham 2021-08-31 21:22:58 UTC 
I can no longer reproduce this particular issue. It has been replaced with Bug 439408 and Bug 438644.

Can anyone confirm? 

Actually maybe this is simply an earlier manifestation of Bug 439408...
Comment 21 Patrick Silva 2021-09-01 10:52:29 UTC 
volume and brightness OSDs are still affected.

Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.22.80
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.3
Graphics Platform: Wayland
Comment 22 Nate Graham 2021-09-01 14:11:07 UTC 
Looking more closely, this is actually the same as Bug 439408. Forward-duping since that one has more info and is being actively investigated.
