—-—-—-— Reply above this line. Applin, Robert (STFC,RAL,ISIS) commented: Hi Adam, I would be happy to do some testing to make sure VirtualGL 3+ works for a Mantid GPU workflow. I am slightly confused why the same error doesn’t occur on the VM for Mantid version 6.6, but it does for 6.7 . I would have thought they would both use the same VirtualGL version installed on the system? Unless the different versions of Mantid could be using different VirtualGL versions?
