Description Giacomo Perale 2007-01-11 02:35:55 UTC

Hello, after the upgrade to compiz 0.3.6 I'm experiencing an X crash when I
start the effects provided by the water plugin. 
The problem is partially reproducible: when I start compiz sometimes everything
works, and sometimes it's affected by the "menus and panels with white shadows"
bug; in this second case X crashes and restarts when I activate the water plugin
with the default key-combination.
I attached gdb to the X process from a different machine, and I could observe
that the first pixel of the wave are draw, then X aborts. gdb log follows.

xorg-server 1.1.99.903 + patch from bug #8991

Reassigning to the r300 driver. Although this may be triggered by bad behaviour
elsewhere, abort() is a bad idea with AIGLX.

Comment 3 Jerome Glisse 2007-01-18 06:08:48 UTC

It seems that the first texture unit isn't enabled at all, likely an
opengl bug in the plugin, anyway we shouldn't do bad things then.
Or it could be that somehow that the mesa contex is in an good
state. A simple gl app to mimick the bug would be nice.

Can you reproduce it with current master of radeon-rewrite branch of mesa?

Comment 5 Giacomo Perale 2009-05-07 14:32:00 UTC

I forgot this bug report, sorry. The problem disappeared sometime around the release of mesa 7.0.

Mass version move, cvs -> git
