Is this bug present in upstream (non-staging) wine?
no, every version I tried of plain wine worked fine
Sorry, I see now that your report said that, and I missed it.
In that case the most helpful thing to do, if you are able, would be to bisect upstream wine against wine-staging, to determine which patch (set) is responsible for the bug. See https://wiki.winehq.org/Wine-Staging#Reporting_and_debugging_bugs_against_Staging and https://wiki.winehq.org/RegressionTesting.
