Trying newer cards with forceGPU would be a good first step.

If you find that this works consistently on newer Matrox cards, then you 
can raise a new bug for this, although it isn't something we are likely 
to work on ourselves. The challenge would be in testing this, since 
Matrox cards are not readily available.

We've done this is a very limited way in the past for issues that 
affected all Intel HD cards, for example.

Good luck with your investigation.
