Application launcher sometimes gets stuck

SUMMARY
The Application Launcher sometimes freezes when opening. Sometimes it's only noticeable because the accent colour at the bottom of the launcher doesn't show, and sometimes the window gets frozen in a faded out white state.

Moving the mouse over the window appears to fix it.


STEPS TO REPRODUCE
1. Open the application launcher several times (the bug doesn't happen every time)

OBSERVED RESULT
Periodically the colour accent at the bottom of the launcher doesn't appear or appears slowly, periodically the window appears white and frozen. 

EXPECTED RESULT
The launcher doesn't freeze, and the colour accent appears instantly.

Interesting. It is just this widget, or do any others on your panel (e.g. the Digital Clock or System Tray) also exhibit the same problem?

Hmm, I wonder if this has any relationship to Bug 435600.
Comment 4 Jonathan Isom 2024-02-10 13:25:08 UTC
I am getting this as well. It happens with both the "Application Launcher" and "Application Menu".  Maybe bug 475318 is related. Other widgets in the dock work fine though.
