Can you run this command and report the result here: /usr/lib/nux/unity_support_test -p

[Jay Taoko (jaytaoko)]

There is no info in the crash report to identify the brand and version of the GPU. However, a similar problem has been observed with GPUs that are missing support for ARB vertex programs. A fix has been submitted to Nux to avoid crashing unity_support_test.
