Rayman 2: Pretty frequent scrambled graphics (e.g., when opening the menu in-game by pressing Start) - seems related to Polygon sort accuracy
I've noticed this issue both while playing the game, just running around in the first level (with the water stream surrounded by grassy platforms) - and predominantly when entering the menu in-game by pressing Start - that the graphics tends to get scrambled quite often, as can be seen in the clip above.
The latter and more consistent example with the menu ought to be a good way to reproduce the issue.
Another video below which is captured from the second level, now with internal resolution increased from stock to 5K, although it doesn't seem to have any effect on the issue - just for reference.
Other examples include when Murphy is communicating through text boxes (acting as tutorials in the game). As they disappear, the graphics gets similarly scrambled.
Changing Polygon sort accuracy from Per-pixel to Per-strip seems to fix the issue so far.
