Occasionally, I can right-click through windows to windows beneath them

Occasionally, I can right-click through Firefox and Okular to Visual Studio Code. I initially thought it might be a problem with VSC, but after seeing something similar with Mutter, [1] I’d like to confirm nobody else using KWin experiences this:

I finally recorded an undeniable reproduction with VSC and Firefox:

However, solely 1 s of it, due to my AOSP distribution’s abysmal QA:

I’ve also captured a screenshot, in case that’s difficult to parse:

This time, Android Studio. The commonality appears to always be Firefox:

However, IDK how to verify this. I presume the KWin Debug Console has something?

Is anything running on Xwayland? There was a bug about input passing through xwayland apps or something like that. Though, I thought this was already fixed.

@Duha, that’s it! xlsclients returns solely code and studio. Would you reopen whatever bug corresponds to this problem?

The bug report I was thinking of is already reopened, although it mentions keyboard events, not mouse click. Maybe give it a quick read if you experience the same, otherwise maybe look for another open bug report.
