Hello! That's a known issue for Nvidia GPUs, for now, you can temporarily fix it changing "gl_interop" to false in config.py, is located in "C:\Users\UserName\AppData\Roaming\Blender Foundation\Blender\2.8x\scripts\addons\rprblender". That's a temporary fix, for now, it will be fixed in one of the future builds. Thank you for request
