Public bug reported:
The "display is jerky in Precise 64 bits but not in the 32 bits version.
By "display is jerky" I mean:
1. Jerky playback with gmplayer: the image refreshes a few times per
second but not 24-30 times as it should. The result is a jerky movement.
2. When moving or resizing a window on the screen, the movement in also
jerky and not fluid. Again it seems that the window is redrawn only a
few times per second.
These symptoms appear ONLY ON THE 64 BITS, not on the 32 bits version.
I checked the CPU consumption during the playback with gmplayer and it's way
less than 100%.
The CPU consumption is similar between the 64 and 32 bits versions.
