Description avlas 2018-09-07 14:51:37 UTC 
Now the different menues appear one by one with a relatively small but visually perceptible latency (first File, then Edit, then Visualize, etc.).

I wish all menues would appear in sync, once a window gains focus, for instance making the loaded menues transiently not visible until they are all ready to be shown.

Can it be linked to compositor speed settings?

> Can it be linked to compositor speed settings?

I wouldn't think so, and I tested it anyways and saw no effect.

The latency I refer to occurs because menues are loaded one after the other. This is fine, but I would recommend to separate the loading (which I assume is slow), from the showing (which I assume can be instantaneous to the human eye). If so, while menues are being imported, the applet should keep them invisible, and once all are loaded, then show them all.

The global menu applet was heavily rewritten since 2018. I can't reproduce such behavior in any app that I tried. I suppose it was fixed at some point in past.
Comment 4 avlas 2022-09-23 06:44:52 UTC 
I still see this effect. Please compare global menu applet and window appmenu applet and then switch back and forth the focus between two different applications. All menu entries appear at once in window appmenu but that's not the case in the global menu
