Wine Version > 5.6 Creates Window-scaling Issue

[allanr]

Since updating Wine from v5.6 to v5.8 or v5.9, I'm experiencing a window-scaling issue with one of the four Windows programs I regularly run on Linux Mint 19.3.

The Windows program starts OK but all the window contents are over-scaled such that they no longer fit into the fixed window size (about 30% out of sight at right and bottom). See attachments.

(The Win program is a utility to configure an external DMX interface connected via Ethernet cable and has run satisfactorily via Wine v4.12.1 thru v5.6. It is available at http://dmxking.com/downloads/eDMX_Configuration.zip)

After some digging around I discovered that Wine v5.6 uses Mono v4.9.4, whereas Wine >= v5.7 use Mono v5.0.0. Using "wine uninstaller" I removed Mono 5.0.0 and installed Mono 4.9.4. Now the program displays and functions correctly!!

So it seems the scaling issue is somehow linked with the latest Mono 5.0.0. version.

Any help or pointers to resolve this problem would be appreciated. In the meantime I'm using Wine 5.9 but with Mono 4.9.4


Thanks,
Allan

There are a couple bugs filed that have to do with appearance in mono 5.0.0, one is here: https://bugs.winehq.org/show_bug.cgi?id=49153

The one comment has a link to a development version, you could try that and see if it also fixes your issue.

Thanks for spotting this bug report. I confirm Mono 5.0.1 restores correct display operation for my WIndows program.

Much appreciated.
