What about making a EnableGpuSandbox switch and have it disabled as the default
?

If you don't want to do that now, wouldn't it be cleaner and easier for us to
patch this back-in for testing if you just commented out line 337 (with a
comment explaining that it's disabled for now) ?

I would leave the rest of the code as is.

Agreed, having the change in only one place makes more sense.
