Bug 1690704

Description of problem:

The Fantasy Grounds II application (https://www.fantasygrounds.com/home/home.php), which is developed with the intent to run under wine, does not work with 4.3, but does work with 4.2/3.16.

How reproducible:
Remove .wine/
Download the installer:
https://www.fantasygrounds.com/filelibrary/FGWebInstall.exe
wine ./FGWebInstall.exe
[I Agree] (agree to EULA)
[Cross-platform compatibility mode for Linux] (check)
[OK][OK] (skip account setup)
(wait for updater to update itself)
[OK][OK] (skip account setup again for final app udpate)
(app will start after that)

Actual results:
- After installing you get a black window. The cursor works and is drawn correctly, but the window is black.

Expected results:
- After installing you get the properly drawn window (not black).

To restart the application:
cd "/home/user/.wine/dosdevices/c:/Program Files (x86)/Fantasy Grounds"
WINEPREFIX="/home/user/.wine" /usr/bin/wine "C:\\Program Files (x86)\\Fantasy Grounds\\FantasyGrounds.exe"

Additional info:
- dnf downgrade wine to wine 3.16 works. Another laptop with 4.2-2.fc29 also works.

In summary:
wine-4.3-1.fc29 -- FG2 broken.
wine-4.2-2.fc29 -- FG2 works.
wine-3.16-1.fc29 -- FG2 works.

Notes:
FG2 has been working for a long time under Wine:
