Diggers (CD32) graphical issues

[lexthehex]

Hi Frode and anyone reading,

Thank you for your continued development of FS-UAE, which I use often.
I've found a bug that affects the PAL version of the Diggers/Oscar CD and does not occur with the Diggers-only NTSC version. On starting the game, there's a 'tunnel sequence' where a mining animation is shown before the intro/speech begins. A press of the fire button - or mouse button - loads the main game.
In the PAL version, the graphics become corrupted at this mining animation sequence, and audio continues playing. The screen is filled with lots of strips of lines and squares (see pictures attached).
If you press a button to load the main game before the animation begins, the issue does not occur. The emulator valiantly tries to restore the screen before the intro ends, but it seems to have a lot of trouble with the graphical corruption.
The game is perfectly playable if you get past this bit, although I haven't played it all the way through yet - that would take me a while!

My version of FS-UAE/FS-UAE Launcher is 3.1.66, running on Ubuntu 20.04 LTS on x86-64 platform.

I've tried Diggers (PAL) in the new FS-UAE 4.0.1. This bug does not occur - woo, yeah!
