Bug ID: 54999
           Summary: Process Explorer from Sysinternals shows a blank
                    window
           Product: Wine
           Version: 8.9
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

This is a regression between wine 8.0 and 8.1.
You MUST make clean WINEPREFIX for this! When the WINEPREFIX was created with
8.0 it also works with 8.1 and later. Only when the WINEPREFIX is created with
8.1 and later the problem occurs.

Tested with procexp64 from

Tested with both the 64bit and 32bit version, same behavior.

--- Comment #1 from Fabian Maurer  ---
The 32bit version seems to only start a 64bit version... It breaks in a 32bit
WINEPREFIX.
So let's make this about the 64bit version.

ntdll: Default to Windows 10.

Probably not very useful though...

--- Comment #3 from Bernhard Übelacker  ---
Compared a relay trace starting from the first CreateWindowEx showed with
windows version set to 10 a difference starting with

0124:0128:Call KERNEL32.LoadLibraryW(140125998 L"uxtheme.dll") ret=140088654
0124:0128:Ret  KERNEL32.LoadLibraryW() retval=26c230000 ret=140088654
0124:0128:Call KERNEL32.GetProcAddress(26c230000,00000084) ret=140088662

After a internet search it looks like function 0x84/132 is
ShouldAppsUseDarkMode.

https://github.com/mintty/mintty/blob/1674fa9019f53b34691f8a8cdeec26c5b1325d...

With following modification procexp64 starts up
and shows the process tree without icons.

diff --git a/dlls/uxtheme/system.c b/dlls/uxtheme/system.c
+
+BOOL WINAPI ShouldAppsUseDarkMode(void)
+{
+    FIXME("stub\n");
+    return FALSE;
+}
diff --git a/dlls/uxtheme/uxtheme.spec b/dlls/uxtheme/uxtheme.spec
+132 stdcall ShouldAppsUseDarkMode()

--- Comment #4 from Bernhard Übelacker  ---
An implementation of ShouldAppsUseDarkMode got committed in b5f4a6a4db.
With wine-8.21 and this commit reverted the empty window is shown.
With regular wine-8.21 Process Explorer shows the process tree (without icons).

Therefore this should be fixed by:

Just a warning for anyone now trying to run Process Explorer.
After a few seconds bug 55000 gets triggered, which kills wineserver.
