Re: 21.5 screen resize issue

After a resize, I see TWO calls to change_frame_size with the correct dimensions, while delay == 1. Each of these sets the f->new_* variables, along with size_change_pending, then returns. Then there's a THIRD call, again with correct dimensions, when delay == 0; that sets size_change_pending to 0 and then we go through a full redisplay. redisplay_frame does: depth = enter_redisplay_critical_section (); and gets back a depth of 3. It proceeds all the way through the CRITICAL REDISPLAY SECTION, then when it's done, calls: exit_redisplay_critical_section (depth); Now, I confirmed that just before that call, f->size_change_pending is still 0. However, when exit_redisplay_critical_section does its unbind_to business, specpdl_depth_counter starts at 13; by the time it walks down to 3, f->size_change_pending has been reset to 1,

but the two f->new_* variables are still 0.
