It makes no difference.

Not sure how to get those.
Anyway, the problem does not seem to be related to the code above.

Actually, this piece of code seems to be a more specific reason
triggering the bug (see the relevant patch attached - that patch makes
the bug disappear). 

I tried your suggestion (no idea how it is different from original code
though). It makes no difference.

A possible hint to why this code fails to resize the frame is that my
WM resizes the frame as soon as it is created. It is not a gradual
resizing with mouse, but rather instant resize to pre-calculated size
(according to layout). I can sometimes even see the frame being created
with much smaller size for a split second followed by resizing it to
target size.

Best,
Ihor
