Bug ID: 49876
           Summary: wine hangs on startup due to crash within
                    EnumDisplaySettingsEx
           Product: Wine
           Version: 5.17
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Using wine 5.17 in Docker, any wine execution hangs on startup.

The bug seems to be related to the detection of display settings, as there is a
crash triggered during "winex11.drv.EnumDisplaySettingsEx".

A workaround is to set "Emulate a virtual desktop" in winecfg.
Things work properly with wine 5.12.

I join the output of WINEDEBUG=+all winecfg.
An interesting excerpt might be the following lines:

Let me know how I can debug further..

It would be helpful to have the same docker image. Could you upload it
somewhere and show the command you used to run wine in docker?

You can use the shell script at
https://raw.githubusercontent.com/pauleve/docker-mtgo/master/run-mtgo
and use it like that:
(it will display the used docker command)

$ bash run-mtgo --shell panard/mtgo:issue102
wine@host:~$ wine --version
wine-5.12
wine@host:~$ winecfg

=> works properly

$ bash run-mtgo --shell panard/mtgo:2020-09-18
wine@host:~$ wine --version
wine-5.17
wine@host:~$ winecfg

=> crashes/hangs

I'm currently bisecting, takes a while; but currently works well with wine
5.13, and starts crashing with 5.14

Installing libxrandr2 within the docker fixes the issue.

Bisecting leads to commit which introduces the crash.

I'm not sure if it is worth fixing, as it seems related to missing installed
dependency. Feel free to close à invalid.

which introduces the crash.
