I am getting a weird slowdown on all non-OpenGL applications while running some OpenGL applications such as Chromium (while playing a YouTube video), Steam and Blender. Games are running perfectly fine, I really don't know what's causing that issue.
Here's a video describing what's happening : http://youtu.be/uuVIgEpBvvM
I'm using a MSI laptop with
- Memory : 6GB DDR3
- CPU : Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz
- Graphics card : ATI Mobility Radeon HD 5870
- glxinfo dump : http://pastebin.com/rR5EqqUL
- Distribution : Debian Wheezy upgraded with Jessie repositories
- Window Manager : Awesome
For the Cataclyst settings, it behaves exactly the same way when I enable or disable Cataclyst A.I., same thing for the Vertical Refresh.
My xorg.conf is the following :
$ cat /etc/X11/xorg.conf
Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection
Section "Extensions"
Option "Composite" "Disable"
EndSection
Section "Module"
EndSection
Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection
Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:1:0:0"
EndSection
Section "Screen"
Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
Monitor "aticonfig-Monitor[0]-0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0

EndSubSection
EndSection
Did I miss something ? What's the exact word to describe that kind of issue ?
