--- Comment #61 from Adam Bolte abolte@systemsaviour.com --- Thanks for your efforts.
With attachment 57770 and attachment 57776 applied to an otherwise clean Wine 2.5 installed on Debian Stretch, I can now run Call of Duty: Modern Warfare 3 and Warhammer 40,000: Space Marine - games I never expected would run. I also tested Saints Row 2 and Saints Row: The Third which also now run fine too.
I did not have to run any chmod commands to get everything going. If it helps, my shell umask is set to 0027. I did have to re-validate Space Marine cache in Steam at one point, but nothing else.
There was some minor graphics corruption in Space Marine, so I tried applying 57770 and 57776 to Wine 2.4 along with the Gallium on Nine patches, and the graphics started rendering correctly (although there was an initial freeze in the main menu which strangely disappeared after hitting Alt+Tab a couple of times). Clearly those are issues unrelated.
