I have a problem. I recently built a new monster PC purely for editting in premiere. Now everything is blazing fast, except for one really annoying bug. During edits, especially if i trim videos, premiere temporarilly shows a side by side view of the footage in the program window. Whenever this happens, which happens a lot, it cannot play back and hangs for sometimes minutes on loading the main window again.
I know my explenation is pretty terrible, so I made a screenshot. Its an old project, but no matter how 'heavy' the footage or the effects are, the problem persists.
I hope anyone knows what could cause this, or even how the comparison is officially called so i can widen my search :)
For some specs:
3TB HDD for footage and project files
SSD for scratch disk
SSD for program files/windows
