Hi

I am getting corrupted output when some windows try to use OpenGL acceleration
(like Chrome, Opera, etc). It looks like it is related to specific window
sizes. 
Some width/height combinations work correctly.

Following errors appear in syslog.

Jun 28 21:23:15 comp1 radeon 0000:01:00.0: evergreen_surface_check_2d:285 cb
height 1088 invalid must be aligned with 128
Jun 28 21:23:15 comp1 radeon 0000:01:00.0: evergreen_cs_track_validate_cb:427
cb[0] invalid (0x000000e7 0x00007b3f 0x000108a0 0x01088468)
Jun 28 21:23:15 comp1 radeon 0000:01:00.0: evergreen_packet3_check:2096 invalid
cmd stream 509
Jun 28 21:23:15 comp1 [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !

P.S. I am on latest radeon git driver
(179b035835bfa99283d44ba2d5ee17e686196535), ATI Radeon 5850 dual-head, Gentoo
x86, xorg-server 1.8.2
