Hey! Guess what? At first test Shotcut version 22.12 seems to fix my memory leak problem under Windows 11! I see that the update notes for it and last month’s version 22.11 mention some memory leaks, so hopefully that was it!
I ran the small “Colours.mp4” test video file through a re-rendering with a slightly different frame rate with no problems - unlike what I’d been seeing using version 22.10.25 (where it got into a loop consuming memory hand over fist). I’ll try to do some more extensive tests with some bigger files in the next few days and report back if I observe any further issues. I hope not!
Wishing everyone a peaceful and relaxing holiday season!
