 It's difficult to say anything concrete without knowing what these fields
are, but the natural question to ask would be how do you set the initial
size of the frame? For example, the size of wxSpinButton is much bigger
with GTK 3 than with GTK 2, so if you hard coded some size for it before,
it would explain why it doesn't fit any more.

 Of those, the switch from GTK 2 to GTK 3 is by far the most important one
and I'm almost certain that if you use GTK 3 with wx 3.2.1 under Ubuntu
22.04 you would see the same problems.

 This just means that there is not enough space for everything, which is
something you see anyhow, but it doesn't really help to understand why does
this happen.
