All other platforms are running correctly, except for X11.

This is linux 4.3 beta3

And this is windows 4.3 beta3

By the way, Wayland can run correctly.

On 4.2.2 this doesn't happen

I can confirm the issue on Fedora 40 KDE Wayland using the X11 display server in multi window mode. It's not reproducible in single window mode or with the Wayland display server (which only supports single window mode).

The issue doesn't happen in 4.3.dev6 and seems reproducible in 4.3.beta1 onwards.

The issue doesn't happen in 4.3.dev6 and seems reproducible in 4.3.beta1 onwards.

I can reproduce this on 4.3.dev6 personally, but not 4.3.dev5 and earlier on Fedora 40 KDE X11.

I bisected the regression to #89058. cc @dalexeev

Hacking the custom tooltip system is the gift that keeps on giving :)

It seems that all popup window can be closed by this method
