Hello,
I know about 2 bugs in X server which are quite reproducible with my programs.
I use CVS from a month ago, but I noticed the first bug months ago already.
I use mga driver.
1/ There is a way to see a screen full of pixmaps (instead of what should be on
the screen).
I can reproduce this bug with sawfish WM.
It has a mode to flip between viewspaces, while moving a window by mouse
movement (and bumping into the border of the screen).
When I do such movement w/ keyboard using mouse emulation, I can trigger this funny
bug. Suddenly, after Sawfish does a series of requests to move windows, and
warp pointer, I see pictures which are used in my (running) firefox browser,
and I explain this that I see "off-screen" pixmaps.
To recover from the wrong display I can either switch to another console, or
cycle resolution with C-M-KP+/-.
2/
DBE (double-buffer extension) operations can make the server segfault.
My guess is, that it is caused by the double-buffered window being too large:
the DBE request are made by my quick & dirty experimental code for Sawfish, to
draw window's title-bar, and the bug happens, when I construct a too large
window (building gtk view-text widget with a long line inside, w/o scrolling
enabled).
Here's the ....
Caught signal 11.

And I would like to ask, if there's a hope to get support for RV370[Radeon
X300SE] in xfree86.
Thanks!
