OK, then that's the root cause, right there: this function continues
to do this:
adjust_frame_glyphs (f);
calculate_costs (f);
SET_FRAME_GARBAGED (f);
f->resized_p = 1;
which marks the frame "garbaged" and requires its complete redisplay,
that starts with clearing it (as you have demonstrated in your
backtrace a few messages ago), and continues by redrawing the tool
bar.
Martin, any ideas why this happens in a toolkit build? I don't
understand how come this condition:
if (new_text_height == FRAME_TEXT_HEIGHT (f)
&& new_text_width == FRAME_TEXT_WIDTH (f)
&& new_root_width == old_root_width
&& (FRAME_PIXEL_HEIGHT (f) ==
FRAME_TEXT_TO_PIXEL_HEIGHT (f, new_text_height))
&& (FRAME_PIXEL_WIDTH (f) ==
FRAME_TEXT_TO_PIXEL_WIDTH (f, new_text_width)))
return;
fails to cause the function to return. The reason must be in the 2
last conditions, which you added in revision 115971.
Glenn, can you show the values of FRAME_PIXEL_HEIGHT (f) and
FRAME_PIXEL_WIDTH (f) in this scenario?
