--- Comment #13 from Ivan Majhen <majhen.ivan at gmail.com> ---
I always had glitches with dri3. I tested it about 30 times in the past year.

Commit 64e1e4db didn't compile. First commit that compiles with current setup
is
https://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=b16609b453bb1a181198cf27778f205dc23fb642

It doesn't compile cleanly.

/usr/src/portagetmp/portage/x11-drivers/xf86-video-ati-9999/work/xf86-video-ati-9999/src/radeon_kms.c:
In function ‘redisplay_dirty’:
/usr/src/portagetmp/portage/x11-drivers/xf86-video-ati-9999/work/xf86-video-ati-9999/src/radeon_kms.c:284:2:
error: too many arguments to function ‘PixmapSyncDirtyHelper’
  PixmapSyncDirtyHelper(dirty, &pixregion);

  removed &pixregion

 error: too few arguments to function ‘PixmapStartDirtyTracking’
  PixmapStartDirtyTracking(ppix, screenpix, 0, 0);

  changed to PixmapStartDirtyTracking2 in drmmode_display.c

After that enabled DRI3 and got completely corrupted screen. 

Screenshot and xorg.log attached.
