I'll do some more testing later this day, I'm out this morning as I was yesterday all day.
Have no clue what to look for at this moment.
Video test file is 720p4audioTracks3satá´´á´° clip if you have this one laying around.

works here ?? (with a random file)

Does it still happen after a reboot ?

[Jan Gruuthuse]

Just back in.
After reboot same issue.
Deleted  both ~/.avidemux6/config2 and ~/.avidemux6/defaultSettings.py
Issue is gone, can't put my finger on why.

Did this affect only the Qt4 version? Maybe the filepicker appeared for some reason on another virtual desktop, blocking the application? Anyway, WFM with a current Qt5 build.

[Jan Gruuthuse]

small quirk(s) that come a live sometimes: Try reboot if fail, delete config2, if still fail delete defaultSettings.py.
sometimes with hardware acceleration (decoding offloaded to GPU) reboot is not enough: actual powerdown is needed of the hardware.
Time shortage (yesterday & today) did not allow thoroughly investigating.

I think we leak GPU buffers
After a while , you need to reboot or restart X11
(only for VDPAU & maybe libva)
