The sreencast

SUMMARY
Seems like regression? I think the latency is introduced in update.
See video in attachment.

SYMPTOMS:
1. Launcher takes a bit while to be ready (start processing key inputs, like arrow keys to change the highlighted icon)
2. This also results in delayed closure of the launcher if you double tap your win key
3. Notice the small bold blue underscore on the app launcher widget is delayed as well

Thanks for the bug report. Hopefully things will work ok from this point forward. I'll set this to NEEDSINFO to send a reminder in 15 days. If the bug happens again, set the report back to REPORTED. Journal logs and the output of top when the bug happens would be helpful, in that case.

On my system (Debian 14 + Plasma 6.5.3), the animation seems to be a bit slow and it gives me the impression that is slow.
I wish it was just a bit faster.

If animations are slower than they were before 6.5.3, that may be a bug. Are they slower now?

Also, is the application menu animation slower than other animations in the UI? 

If they have always been slow, you can adjust the animations in Quick Settings.
