Hello Dege,
I don't know if you're aware of it, but we are distributing you libs as part of a package/patch to make the old game from 1997 Star Wars Rebellion updated to better work with current OS.

My github is here :
https://github.com/MetasharpNet/StarWarsRebellionEditor.NET/

We observe strange rendering in the game. Would you like to discuss to see it anything can be done about it?
My discord is : metasharp (if you are on discord as well).

Issues we identified:
- color rendering of BMP indexed on 256 adobe color tables (.act).
- graphic artifacts with loaded screens
- texture/light flickering (we might have found a config setting that solves 95% of it, but it's interesting to discuss)
- full screen rendering failing over HDMI while working over DisplayPort

Best regards,
