I understand the patch, and I think that it's okay as far as it does what
the OP (kub) wants to achieve.

kub wrote: "In the context of a resize with no new area covered, Xlib does
not need to send the expose event as no new area is to be redrawn."

Yes, that's okay, and I understand. But then: "In case of FLTK widgets
this is a wrong assumption."

Why? I'd like to understand and replicate the problem before applying a
patch that would otherwise (maybe) result in too much drawing (slowing
down the X server connection) for other WM's.

So, what exactly are you doing, and why is the assumption wrong? AFAICT
there must be a resize() involved that is in fact a shrinking of the
window - after the window has been shown. Are there other widgets in the
window that are resized, but are not drawn correctly?

Questions to the OP (kub):

- what are the effects that you see?
- can you post a small example program that shows the effect? 
- is this still a problem, or is it maybe fixed otherwise (new FVWM
version)?
- is it only visible with FVWM ?
