Red screen on MAME boot

Hi,

When trying to load a MAME game in RetroArch (using the latest MAME core) it boots to a red screen. Opening the RetroArch menu and immediately returning to the game fixes the problem. retroarch_debug.exe doesn’t seem to have this issue. Any ideas? Other MAME cores (eg 2014) don’t have this issue.

Thanks

Realised this was caused by having the ‘Video Threaded’ option on. Turning this off fixed it.

Ah, glad you got it fixed, and thanks for posting your solution!
