[winswitch] Problem on Polaris

[sivmu]

changing csc-modules did not help.

the output of xpra info | grep csc after the changes:

client.encoding.csc_atoms=1
client.encoding.full_csc_modes.h265=('RGB',)
video.encoding.csc-module.cython=disabled
video.encoding.csc-module.opencl=not found
video.encoding.csc-module.swscale=disabled


still the same error message.
However after removing python2-pyopencl, the error message disapeared,
but the issue with the slow response still exists.

Please note, after removing the amd gpu and using the internal intel
gpu, xpra works fine and connects in less then a second.

So the issue is definitly related to the gpu.
