--- Comment #10 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- (In reply to Jean DELVARE from comment #9)
The WINE_SIMULATE_WRITECOPY=1 trick doesn't work for me (wine-staging 9.0-rc2, openSUSE package). Do I understand correctly that the code handling this environment variable is a downstream workaround and isn't present in upstream wine yet?
Hello,
Yes, that is a Valve/Proton hack. It's not included in wine or wine-staging. GloriousEggroll's wine-ge-custom includes it. I don't know about others wine forks.
If you want the hack in wine or wine-staging, you'll have to apply the patch from comment 7 on the source code and compile it. Note that the patch won't apply cleanly on wine-staging.
Regards.
