Sounds like you have the same bug that affects other Unreal Engine 4 games:

The other bug is now marked fixed. Can you test wine-git or next release 1.9.23
(not out yet)?

This error is now also occurring for Epic Games Launcher. I think that it has
been introduced by a certain UE4 version.

Confirming and added downloadlink. First I thought it was bug in msctf but
native doesn`t help, and I can`t figure out where the crash comes from.

Tried Epic Launcher from bug 40376 against wine-staging 2.6. And this bug is
still valid.

I tried it also again, as a guess it might be a consequence of
EnumDisplayDevices or EnumDisplayMonitors returning wrong stuff.

I tried very poor and sad hack below, and it seems to get a tiny bit further,
to crash in d3d11. I cannot run any d3d11 things because of my poor GPU, so
maybe someone else with better computer could try the hack to see what happens;

sad and poor and completely wrong hacks, only to pinpoint the bug

@wineluukku: I got that too, but i`m now able to get the window up with the
poor hacks from the attachments (which are quite wrong, but the app starts to
run)

I used LIBGL_ALWAYS_SOFTWARE=1 wine EpicGamesLauncher.exe and also set the
registrykey MaxVersionGL to 30002 (hexadecimal)

With the hacks the launcher starts to download things but than fails,
apparently because .NET is not installed. Needs further testing.

AFAICT three bugs to solve:

1. EnumDisplayMonitors (or the like) might return wrong stuff?
2. Undocumented  IsThreadDesktopComposited needs stubbed
e. Undocumented SetWindowCompositionAttribute needs stubbed

A last remark: the stubs for undocumented are apparently not needed. I didn`t
install in a clean wineprefix, after installing in a clean wine-prefix only
hack from comment 10 is needed.

After installing dotnet20 I got the login-window up using wine-staging (+hack),
in vanilla wine it doesnt run

Fresh wineprefix this time, worked around bug 38648. Used wine-2.6-git with the
hack mentioned before from this bug report. And Now I am able to see a launcher
too and it's updating files.

This bug also exposed bug 40873 and bug 41173.

Didnt try to push it further with the staging patches.

Louis could you do something about bugs bug 41172 and bug 40376. There is no
need to reinvet the wheel over and over again. Wasting everyone's time.

@Louis Lenders regarding D3D11: did you try to run with "-OpenGL"? Before this
bug occurred, I used the parameters "-OpenGL -SkipBuildPatchPrereq".

Hi, I didn`t try that. The loginwindow worked with the command i used; I guess
if you want to play a game one can use the parameters you provided(?) Anyway,
first this crash has to be fixed properly to get progress in this bugreport

--- Comment #17 from Yujiang Wang  ---
After debugging with my UE4 build, I found the bug is related to
EnumDisplayDevicesW:

The engine uses an ugly way to get the device name for monitors. It extracts
the name from the device id by finding a second backslash starting from
position 8:
Engine\Source\Runtime\Core\Private\Windows\WindowsApplication.cpp:
GetMonitorsInfo: 611
Info.ID = FString::Printf(TEXT("%s"), Monitor.DeviceID);
Info.Name = Info.ID.Mid (8, Info.ID.Find (TEXT("\"),
ESearchCase::CaseSensitive, ESearchDir::FromStart, 9) - 8);

The Monitor.DeviceID comes from
EnumDisplayDevices(DisplayDevice.DeviceName, MonitorIndex, &Monitor, 0)

On Windows, Monitor.DeviceID is set to something like:
MONITOR\HWP3183{4d36e96e-e325-11ce-bfc1-08002be10318}\0001
while wine set it to:
MONITOR\WINE0000

Clearly we can see there is no second backslash to be found, thus causing a
crash.

The device id is defined at:

wine-staging/patches/gdi32-MultiMonitor/0003-user32-Implement-EnumDisplayDevicesW-based-on-EnumDi.patch:
29
+static const WCHAR display_device_deviceid[] =
{'M','O','N','I','T','O','R','\','W','I','N','E','%','0','4','d',0};

I changed it by just adding a backslash:

+static const WCHAR display_device_deviceid[] =
{'M','O','N','I','T','O','R','\','W','I','N','E','%','0','4','d','\',0};

Now the engine gets through. Maybe we can fake a guid here to get more
robustness?

I also prepared a minimal unreal engine 4 project build for you: (UE4 master
branch 4.17 2017-05-22 VS2015 Windows 10)
https://www.dropbox.com/s/2g2tl7gz7bsiop5/WineTest.7z?dl=0
This build comes along with pdb files. I think it will be useful for you.

Good luck!

Note: This build has fixed the EnumDisplayDevicesW bug on the engine side, so
you can concentrate on the shader part.
