I’ve successfully installed Retroarch on my Amazon Fire TV Stick 4K. The installed emulators for NES, SNES work perfectly.
However, there is a general display problem when using CRT shaders. The zfast-crt shader serves as an example, but the same display problem also occurs with the crt-pi shader.
As you can see on the images (the red line within of the images is used for marking only) about 40% of the screen (right side of the screen is affected) is noticeably darker than the rest.
This phenomenon also occurs when using crt-pi shader instead of zfast-crt.
Anyone who can help me to solve this problem?
Many thanks! Sebastian
