I think it fits in here:
Running Linux Mint 18.1 with Cinnamon
Can run Shotcut, but everytime the Screensaver starts, the Shotcuts GUI “disappears”; any rendering-process continues running though…
Between Mint/Cinnamon and Shotcut, there seems to be something “not playing well together”… (can’t supply a debug-log as the rendering-process is still going (and as it only runs on one core on my system, i’ll wait the 3 hours - maybe the vid is finished after it (if not, i’ll have to restart tomorrow… (any hint to start shotcut with a higher verbose (getting a log-file written would be great)?)
