[Intel-gfx] kwin compositing broken with 2.8.0 (and git)

[Thomas Fjellstrom]

Ever since about a week ago or possibly two, the intel gfx driver on my GM45 
(4500MHD  gpu) has been either unstable with compositing, or just fails to 
initialize composting altogether.

I had been running the git driver for a little while to get working KMS, and 
about the same time the DRI2 changes hit, compositing in kwin4 started to get 
rather unstable, (screen freezes) and now since a few days ago, compositing 
won't initialize at all, and glxgears seems to run at a low low 300fps. 
glxinfo does say direct rendering is enabled.

I'll probably post a bug on this soon following the "how to report a bug" doc, 
but I just thought I'd ask here if anyone knows what might be the cause, or if 
its fixed now? (I last checked git a couple days ago).

as a side note, with that notice that intel git got FBO support, I updated and 
tried it out. It seems that using an FBO in one opensource lib (allegro 4.9) 
is slower than other methods, including downloading, modifying, and re 
uploading texture data. But I decided that was probably due to a mistake on my 
part when installing the intel drivers from git, so I've downgraded back to 
what is in Debian sid (2.8.0), and there's no real changes.

Thanks for the hard work on the driver so far :)
