130177 - Mac Zooming / clipping / drawing bug

Status: NEW

(Core :: XUL, defect)

Description

[Robert John Churchill]

Try this on Mac OS X:

o  open a browser window. Make sure it isn't in the zoomed state.
o  open the Find dialog
o  click the (now-behind) browser window's zoom box

What'll happen: the browser window will zoom, but the foreground Find dialog
will not draw its contents... you'll be left with merely a gray background.

I can add that it's probably timing dependent: it doesn't happen to me every
time I zoom the browser window with Find open. In fact it seldom happens the
first time. Notice that it also happens (to me) with modal windows (sheets):
open the Open Location dialog and zoom up and down a few times. Dialog goes
blank gray.

As far as I can tell, it isn't timing related... and seems to be more a function
of the dimensions of the background-about-to-be-zoomed browser window.  If you
make the browser window really small, open the Find dialog, then zoom the
browser window, it seems to clip (or draw to gray) the Find window based upon
the bounds of the pre-zoomed browser window.

Hmmm... also, once the Find dialog has been "grayed"... merely mousing over the
elements in the dialog causes them to draw.

Still occurs using FizzillaCFM/2002061014. Guessing XP Toolkit/Widgets.

Works for me in build 20040405 on Mac OS X 10.2.8. Reporter, is this still a
problem for you ?
