Animating still images isn't working

I've updated drivers, it didn't help. I did some further tests: If I animate only scale, playback doesn't work. If I animate any other property: playback works. If I animate scale and any other property: playback works.
So, the problem happens when animating scale alone, and only when using still images.

Strange, 23.3 B61 works normally, I'll update the graphics driver and see if it helps with the Beta

jpg. Much larger than sequence. Using spacebar playback.

PC Win10 btw.

Some problems are just weird!

Hey Stan, thank you for the update, but it still doesn't work on my side. Are you animating a video or a still image? Because with videos it's working fine, but with still images (or even color mattes) the playback isn't working.

I just tested in 48. I can keyframe scale and position. Both show on playback.

Just updated to B48, the problem isn't resolved...
