I’m still having this problem unfortunately. I seemed to have fixed it by switching from the cg version of crt-royale to the glsl version and it worked fine regardless of the core I was using(beetle, higan, genplusgx ect.) However, the problem came back today when I accidentally hit one of the hotkeys which cycled to a different shader. When I tried to change it back, the image wouldn’t display properly.
I figured it might help to switch to a newer version of retroarch, so Installed a 1.7.1. I then loaded up game in beetle, loaded crt-royale, adjusted the settings to my liking, and it worked the way it was supposed to. I then loaded sonic in genplus gx and the shader settings didn’t carry over, and when I tried tried to apply them, they didn’t display properly again, nor would they work right when I went back to beetle.
Oddly enough, when I take a screenshot in retroarch, this image comes out looking the way it’s supposed to.
Anyone know what’s going on here?
