Bug ID: 51038
           Summary: without virtual desktop, occluding black box in 3D
                    view.  With virtual desktop, missing icons in 2D view
           Product: Wine
           Version: 6.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

This bug occurs for all versions of wine, including wine-6.6 (Staging).  It
does not cause a crash, but causes graphics problems which makes the games
unplayable.

I can't find a winecfg Graphics setting that works for BOTH 2D and 3D view in
two classic open source flight sims.

The source code of these two flight sims, Rowan's Mig Alley and Rowan's Battle
of Britain, is at these links:

https://github.com/gondur/mig_src

https://github.com/gondur/BOB_Src

In both games play alternates between a 3D flight sim view and a 2D strategy
board game view.  For both games, winecfg Graphics decorate windows should be
turned off.  Per the title of this bug, 3D view is usable only if virtual
desktop is turned on, while 2D view works only if virtual desktop is turned
off.

A workaround that usually works is to use a dual monitor setup, set 2D and 3D
resolution to 1024x768 in the game, and turn virtual desktop off.  With these
settings the 3D occluding black box conveniently moves to the second monitor,
thus both 2D and 3D view are correct.

To reproduce this bug, on a Ubuntu 20.04 partition download and unpack this tar
file
https://www.mediafire.com/file/p6jkteimq89xjsm/esports-for-engineers-v40.tar...

If you want to verify that this file is not corrupted,run 
"sha256sum esports-for-engineers-v40.tar.gz".  
Then check that the output is is
4b1172ade547dfd0a352d11bc9cae1501693e048c8c4996c2c6a9ee287d67826
esports-for-engineers-v40.tar.gz

cd to esports-for-engineers-v40 and install apt packages as instructed in the
file
ubuntu_20_04_LTS_PackageInstall.sh

To install Rowan's Battle of Britain, run the script
esports-for-engineers-v40/THU/BattleOfBritain/battleOfBritain.sh

To install Rowan's Mig Alley, a similar game with the same bug, run the script
esports-for-engineers-v40/THU/MigAlley/mig.sh

How can I get both the 2D and the 3D view working correctly without using the
dual monitor setup workaround described above? I tried running winecfg on a
second monitor and changing the setting when I switched between 2D and 3D view,
but this had no effect.

A new version of the tar file containing the Battle of Britain binaries has
been released, thus the link to the tar file has changed.  To download the
tar.gz file containing the Battle of Britain binaries, search on "esports for
engineers" at github.

This bug still occurs with the latest versions of Ubuntu and wine, namely
Ubuntu 21.04 and winehq-staging 6.11

Please look at this bug.
