--- Comment #2 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- Hello,
I believe the issue is that some functions return/use the current display size and not the virtual desktop size. All of my older prefixes opens the steam windows outside the virtual desktop after an update to wine 9.1, although they were working fine before.
Regards.
