> CUDA error: invalid device symbol, CUDAClearDevice.cu line 62
As far as I understand, the current VMD 1.9.1 CUDA code is incompatible with the latest CUDA runtime and driver from Nvidia. So the message is seen everywhere since a 600 series card. The message tells that the syntax of the used commands has changed and the "old" code isn't working anymore. This is expected to be fixed with 1.9.2.
Regarding the "composite", you would notice if it would be a problem for you. For instance due transparent windows.
