Comment 39 for bug 850649

This bug is concerning low performance and graphical corruption of output in terminal like programs on ANY desktop using ANY driver on ANY number of screens!

Having followed discussions for this bug and bug #877438 for some time i am very confident that this is not a duplicate.

I have removed the duplicate status.

Please notice that there are several separate bugs that have similar symptoms but are not the same:

 * If you have an *nVidia* card and *multi headed* setup you may want to check out bug #877438
 * For slow performance in any *multi headed* setup using *Unity* on any driver check out bug #874619

These bugs are not duplicates but have somewhat similar symptoms. It is possible that you can be affected by more than one if these at same time, but they are not the same bug!
