IUP internally has an estimate of the button border space, so it can
compute the button size from inside out. Maybe in your GTK3 system these
minimum borders are larger than IUP estimate. So the result layout where
the buttons sizes failure.
Can you compile the "sample.c" test from the examples (and send the
screenshot)? It will include several other controls and I can compare with
the results I have here, so I can make sure only buttons suffer that
problem. Then the next step is to fix the estimate for that system somehow.
Best,
