Personally I think the secondary reasons (1-3) are enough for merging
this, so I've done it.

I've tested all my systems with Intel graphics hardware, and none
exhibits the memory wipe issue reported in #6460 *without* this fix.
Hence I leave the ticket open until we have more confirmations that it
actually fixes the issue.

Cheers!
