Does the problem happen in vanilla Wine (non-Staging) too?
Non-staging wine can't even start Battle.net Launcher. It crashes with "Program Error: The program Battle.net.exe has encountered a serious problem and needs to close. We are sorry for inconvenience".
Some time ago I had to apply "chromium write-copy patch" to non-staging wine to get it working. Since the patch seems to be already included into wine-staging, I stopped to patch non-staging wine and switched to staging.
Could you please run a regression test to find which commit caused the issue?
Hopefully I can try to bisect wine-staging between 10.4 and 10.5 this week.
