So I saw you hat lots of time reworking the GUI, which is a mess btw and lots of things are counterintuitive and there are now many design flaws compared to the old GUI...
But the new version just doesn't play HEVC files anymore, there just comes sound and a picture, nothing else. This worked before...
Could you, now that you took so much time into rebuilding the UI, maybe also include an option to disable the annoying GUI triggering by mouse movements?
