wxGLCanvas inside wxPopupWindow: wrong positioning on Wayland. (Issue #24102)
dsa-t
Description
See this code for the cube sample: cube-popup.zip
It creates a wxPopupWindow with a wxGLCanvas which moves it with the mouse cursor, aka hides, sets position, shows (we use that in KiCad for hover previews, on other platforms hiding is not necessary).
The GL canvas is positioned wrong, as seen in the video, also the menu doesn't show up:
GDK_BACKEND=wayland samples/opengl/cube/cube

Works better on XWayland:
GDK_BACKEND=x11 samples/opengl/cube/cube

On GNOME, it's flickering.

Also would be good to know if wxWidgets can move the popup window without hiding it, or is it the usual Wayland limitation?

And on Sway + Wayland GDK_BACKEND, the popup shows up once, does not move, and disappears when mouse cursor leaves the top-level window.
