Does the problem happen when running on X11? You can force X11 by
setting environment variable:
GDK_BACKEND=x11
before starting your program.
That was an excellent question that found part of the problem:
GDK_BACKEND was already set to x11 due to my debugging. If I unset the
environment variable the problem disappears => Logged in into a
non-wayland session and the problem appeared again.
OK, so just to confirm: the problem occurs with X11 but NOT with Wayland?
