Ubuntu 11.4 ( with cairo-1.11.2 ) radeonHD 5570 with catalyst 11.6
steps to reproduce :
- open a new file
- draw a rectangle or another figure
- zoom-in - before the mouse release the artifacts occasionally will occur
- probably is just because of ATI / AMD drivers
Confirmed with Radeon HD 4850 with the same Catalyst version. This only appears if you use the rubberband zoom (from the zoom tool), not Ctrl + wheel.
