Hello,
On Sat Nov 27 22:47:59 2004 UTC, there was a big commit into Mesa CVS by
brianp, with the following comment:
> Remove _mesa_ResizeBuffersMESA() call from _mesa_set_viewport().
> Now, the driver's Viewport routine should call _mesa_ResizeBuffersMESA()
> if necessary.
The r200 driver fails to do that. Thls leads e.g. to the buildings outside
the bottom-left 800x600 rectangle disappearing in bzflag, and screenshots
showing only that rectangle. The fix (stolen from the "radeon" directory)
is attached, please apply.
Unfortunately, I can't test anything except r200, but please check the
"i915" and "x11" directories for the same type of a bug.
