[Bug 444139] Re: (Needs KMS) Background and full screen apps don't show up when Normal Visual Effects on (Radeon 7500)

 

I don't know exactly how to determine video memory size, but I believe
it is an old 64MB card as card ID is R9200SE/64B/64M.

lspci gives

~$ lspci -v -v

Just repeat my previous post:
Option "AGPSize" "8" => doesn't work (black screen with compiz)
Option "AGPSize" "16" or "32" => desktop image is back.

I didn't test another options as "BusType", "AccelMethod" or
"MigrationHeuristic". Just let me know if it is needed.
