Combining ALLEGRO_GTK_TOPLEVEL and ALLEGRO_RESIZABLE causes mouse event Y position to be offset

[chruffins]

I'm working on a project where the display uses the menu functionality and is intended to be resizable as well, but combining these flags in al_set_new_display_flags causes mouse events to report the wrong position. ALLEGRO_GTK_TOPLEVEL by itself as well as ALLEGRO_RESIZABLE by itself work normally. In all of these cases, I'm also using ALLEGRO_WINDOWED and ALLEGRO_PROGRAMMABLE_PIPELINE.

The circle directly above my cursor shows the reported xy-coordinate that I get from mouse events.

I can't seem to reproduce this on the master build. What version are you using? Also, what desktop environment is it (GNOME? KDE? Cinnamon?)

I'm using 5.2.8, and this is on GNOME

I tried this with that configuration, and am still having trouble reproducing this. Is it at all possible to get access to your code?
