After upgrading from 13.2 on my old 32 bit Acer TravelMate 2410 all video playback lags terribly including for the same videos which previously played in 13.2 flawlessly. I use smplayer in xfce as I always have. I tried mpv Media Player - same result. I tried also the “Videos” application however it gives only sound output.
In case that matters:

This is an old computer but these videos and thousands of others have always played without problems on it, so it is definitely a software issue.
How can I fix this?
