:atrif, since this bug is a regression, could you fill (if possible) the regressed_by field?

I guess this is wontfix for 99, since it's an S4.

This is a variant of Bug 1754950 and there isn't a fix for that:

I don't think it's a regression.

I can reproduce the issue with xwayland and wayland Window Protocol as well. I don't know the regressor here unfortunately.

[Martin Stránský [:stransky] (ni? me)]

If you see that on XWyaland it's not related to Wayland but rather a general popup handling.
I wonder if Windows is affected too.
