Using AMD's proprietary fglrx driver with compositing enabled, I am seeing huge amounts of corruption in Open GL applications when running full screen-- see attached screenshot-- and very slow performance when running them windowed. Here are some details:
OS: Mint 13 "Maya" x64 Cinnamon
PC: Clevo P150HM
GPU: Radeon 6990m
Fglrx package version: 2:8.960-0ubuntu1
Applications with problem: Any OpenGL application, such as Minecraft, Kega Fusion, etc.
Disabling compositing via the below xorg.conf directive completely solves the problem-- Kega Fusion runs at a bajillion (yes, bajillion) FPS, and in full screen with zero corruption. But then I lose all of my cool desktop effects Yes, I want my cake and I want to eat it too! Why can't I have cool desktop effects like Cinnamon (versus the fallback to "classic" Gnome) and working OpenGL support?
- Code: Select all
Option "Composite" "0"
Also, even with compositing enabled glxinfo reports "direct rendering: Yes", so I swear I'm running with hardware acceleration in all cases. I wish I could just get compositing to ignore OpenGL applications somehow.
Anyone have any ideas? Thanks in advance!
