This started getting really bad when I moved up to C 9.5. I’ve had occasional problems before, but nothing so purrsistent. It’s happening several times a day, often for quite long periods and is really hindering my workflow. Sometimes a loud bit of audio seems to clear it, but then it returns periodically throughout the working day.
Apart from obscuring the Arrange page, everything else seems graphically to be ok, my mixer on a separate monitor is rarely affected. It does seems to follow the mouse pointer a lot.
Has anybody else experienced similar problems? I am guessing that it could affect both Windows and Mac OS.
