Display flickers and shakes when using Shaders on Flycast Core #1045

Hello everyone,

I noticed that in all games, when having any shader activated, display flickers and shakes on Flycast, I had the CRT Geom and screen was shaking, with other shaders the problem is present as well.

Thank you so much in advance.

Not a Flycast issue, not even an issue at all, it's just the shaders trying to imitate the interlaced image (I believe it starts happening when you select a resolution higher than 320p in the core options). But anyway, while you're ingame using CRT Geom go to Quick Menu > Shaders > Shaders Parameters and change "CRTGeom Interlacing Simulation" to "0.00" (which means "OFF" in that case), and it should stop the flickering ;)

Thank you much my friend, problem solved, and also I learned something new, I've never touch or changed those options or parameters, next time I will know. Take care.
