We had a lot of reports on HD4000 as well, listed as duplicates of 803944.
DX11 support is not relevant here at all since we are only use DX9.

Since your fix explicitly checks for Intel hardware, it doesn't make any 
sense to use it without unblocking them.
Moreover, I can't see how this bug (8146042) can be reproduced without 
modified build which unblocks Intel hardware.
