I've captured some info from the console, hope that would help. Any idea on why, and is there any solution to fix it?
Yep. Take a look at the "GL_interop" setting in viewport sampling. You need to disable this. It's mentioned here: RadeonProRenderBlenderAddon/Changelog.md at master · GPUOpen-LibrariesAndSDKs/RadeonProRenderBlender...
Yes! that's solved! Finally! big thx.
