Yotam, Thanks for Your reply. That is the issue. If nouveau would be as fast and fluently working as nvidia drivers (2D acceleration), you would certainly see the sluggishness. I have also seen this with open source radeon driver with ATI HD2600 pro graphics card.
The rendering issue is more severe with nvidia drivers. But nvidia-current_256-35 is older than libcairo2 1.9 branch. It can only be seen cairo has evolved into a direction where it ended up being incompatible with nvidia drivers. Note also that, libcairo issues may be apparent only in ubuntu-family, at least not in arch-linux. So where is the bug then? Who knows. -- nvidia 256.35 driver is slow and renders elements incorrectly https://bugs.launchpad.net/bugs/612614 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
