Tilted notification icon

Sometimes, the notification icon is tilted (see attachment). Looks like it's stuck in some frame in the animation.
Don't know how to reproduce, yet.

Hi!
Did this happen in a X11 session or a Wayland one? There are bugs specific to each session, so this info helps us narrow it down.

X11 session, with PLASMA_USE_QT_SCALING=1

I've also seen this occasionally for at least a year now, both on Wayland and X11 sessions.

This seems fixed in Plasma 6. Can you confirm, Jin? Have you seen it at all in any versions of Plasma 6?

It happens much less often, but I have seen it at least once in 6.1. Unfortunately I'm still unable to reproduce it consistently.

It seems to happen when the system is under heavy load (e.g. when building KDE). So I guess it's a timing issue that might trigger when plasmashell is very slowed down.

Darn. Thanks anyway for the update.
Comment 8 Jin Liu 2025-02-17 07:09:57 UTC
I've never seen this again in Plasma 6.2 and 6.3. So perhaps it has fixed itself, and I'm closing this now.
