The Window one fixes it, but it's very undesirable because it runs windowed instead of fullscreen, I see the taskbar, and so on. Any other solution?
Yes, a lot. This all depends on YOUR setup
- Try "Window (no border)" mode in AttractMode
- Set RetroArch to use the same resolution as your OS
- Set RetroArch to use "full screen" mode
- use a different video driver in RetroArch (i.e. gl, d3d9. d3d11, d3d12, sdl2)
- make sure you have the latest directX drivers installed and working properly if you're using any of the RetroArch d3d* video drivers
- make sure you have the latest video card drivers installed for the OS (and check their setting if they use an application to change them instead of the OS tools)
- make sure that AttractMode is using the same video resolution as RetroArch
- make sure that you have the correct/latest MS Visual C++ redistributable installed for RetroArch
There are many variables in play. Only you have your exact setup to test them.
