Supermium 122.0.6261.85 crashes on XPSP3 during startup when used with --in-process-gpu

[JoachimHenze]

Using
--in-process-gpu
as a startup flag on Supermium 122.0.6261.85 (32bit) on XPSP3 makes the browser crash during startup.

The debug.log gets the following line logged for each startup-crash:
[0305/180658.687:ERROR:crashpad_client_win.cc(476)] InitializeProcThreadAttributeList (size): Für das angegebene Programm ist eine neuere Version von Windows erforderlich. (0x47E)

The UI starts up nevertheless, and the browser can browse afterwards. So it is (just) some subcomponent that is crashing here.

The same flag in the older "Supermium 121.0.6167.81 Hotfix" didn't cause a crash.

Same error on WinXp x86 with v122 and without any additional flags. Just starting Chrome.exe.
Or on other machine start Chrome_proxy.exe, than do something with UI, ant it crashes with error.
debug.log in English:

[0305/195254.482:ERROR:crashpad_client_win.cc(476)] InitializeProcThreadAttributeList (size): The specified program requires a newer version of Windows. (0x47E)
[0305/195306.311:ERROR:crashpad_client_win.cc(144)] crash server failed to launch, self-terminating

"The specified program requires a newer version of Windows. (0x47E)" . --WTF ?

Ok... I'm go to source code and found this file:
\third_party\crashpad\crashpad\client\crashpad_client_win.cc

Then found this line some code above before error happened:
GET_FUNCTION(L"kernel32.dll", ::InitializeProcThreadAttributeList);
So the code tryes to load original kernel32.dll, without your (@win32ss) API-wrapper progwrp.dll, resulting in error ?

WinXp x86 with v122 and without any additional flags [does also crash for @IDA-RE-things ]

That's definitely different here for me on my XPSP3. I don't have a crash at startup when I run it without any flags.
Maybe it depends on the used graphics card that it always crashes for you @IDA-RE-things . I just wanted to make that 'little difference' between our two setups clear, right from the start.

This crash was fixed by
Supermium 122.0.6261.85 Hotfix (R2)
I can again start the browser on XPSP3 with--in-process-gpu to save a few megabytes of RAM.
Ticket closed. Thanks!
