I've just installed the latest WineBottler v2.0 from https://winebottler.kronenberg.org/downloads.
I clicked on the supplied Steam install button, and ended up with a new application in my application folder - I called it Steam-winebottler.app because I've already got the standard Mac Steam.app.
Steam-winebottler.app launched fine, did various updates, and eventually gave me what looks like a log-in window without any of the usual text.
What I mean is I can see the Steam logo, the Valve logo, and what looks like boxes for password and username entry, but not text saying "Password" or "User name" or "Click to continue" or anything like that.
Here's a screenshot:
https://appdb.winehq.org/objectManager.php?sClass=version&iId=19444
mentions a problem: Steam client window(s) do(es)n't render any text.
which says "Ensure Steam client is launched as follows...
wine Steam.exe -no-dwrite"
It looks like that's the problem I've got, but I can't see a way to apply the fix when using the WineBottler approach.
I'd appreciate any clues.
Thank you.
