Well, it's obviously something wrong with the blits using source color key. I assume it's a driver issue because it only seems to affect the Radeon RX 5xxx series. I added a potential auto-detection of the problem for this case, and worked around it by emulating the broken feature in software if needed.

Please retest with the latest experimental release, since I don't have appropriate hardware to reproduce the issue.

Looks like it is working fine now. Thank you for the fix

jcgo16 commented 3 years ago

Let me know if you need the new log file for the new fix

No, if it works then it's fine. Thanks for the feedback!
