So I have been experiencing my share of crashes (not as bad as X1 was though) and I thought I would try the quickfix:
After application I noticed all sorts of graphic corruption - Sonar started showing black rectangles instead of graphics in the console view and a couple of times the track view became very graphically corrupt. Also, I would get a crash everytime I tried to select a different output source in the console view - just clicking the drop down menu would crash Sonar.
I have since reverted to before the quickfix and everything is working again.
Anyone else with the quickfix have a similar experience?
