I am running Ubuntu 16.04 on a VMware workstation player VM on windows 10. When I run some GUI programs (have observed this on Spyder and Chromium) am getting the message "context mismatch in svga_sampler_view_destroy" is repeatedly printed to the console.
It seems to be related to virtualization as it goes away if turn off 3D display acceleration. I don't want to turn off acceleration as it makes a big difference to the video performance.
