Description JT Hundley 2024-09-30 19:05:37 UTC 
SUMMARY
When using the mousewheel to change activities in the activity pager, the first mousewheel event is ignored.

STEPS TO REPRODUCE
1. Click in another window to give it focus.
2. Move the mouse over the activity pager and scroll it.

OBSERVED RESULT
The first time you move the mousewheel nothing happens. The 2nd time the activity is changed as it is supposed to.

EXPECTED RESULT
I expected the activity to change on the first mousewheel event as it did up until recently.

Cannot reproduce on Wayland. Likely X11-only. Can you still reproduce it on Wayland?
Comment 2 JT Hundley 2024-10-01 02:24:13 UTC 
I just logged in using Wayland and the applet worked as expected, I could not reproduce the issue. I think you're right that it's X11-only.

Last night I upgraded qt6-base (6.7.3-1 -> 6.7.3-2) and the problem seems to be gone!

Cool, I guess it was a Qt bug. Thanks for following up!
