Ok, this ia bug report for the 6.0 client - same issue I also had on the older one, but - well - now everything else works, so I woul like to use the 3cx voip client, as long as you do not provide OCS integration. My problem is that the Application is unstable graphically. The window is "flashing" away, every 21-3 seconds. For just a socuple of frames - no clue how to make a video of that even. It is the first application I ever saw doing so. Looks like someone is putting it to "hidden" every 120 frames or so for 2-3 frames, or the redfraw works wonky. I run it on a 2008 Standard Server, configured to desktop mode (i.e. driver installed, desktop experience enabled, vista aero theme enabled). This is the only app I ever saw doing so THe application otherwise has zero issues. Any idea what this is? I would like making a video to show hthat ,butI fear it will not be visible on video - it just disappears for a very short while every couple of seconds.
