Bug ID: 48613 Summary: Zwift: ZwiftApp.exe startup crash on intel graphics hardware Product: Wine Version: 5.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: wentam42@gmail.com Distribution: ---
Created attachment 66453 --> https://bugs.winehq.org/attachment.cgi?id=66453 Log of crash with +relay
On some machines, running ZwiftApp.exe (via RunWithProcess as described here: https://bugs.winehq.org/show_bug.cgi?id=46313) results in a page fault not long after launch.
As far as I can tell, this only happens on machines with intel graphics hardware (see bug 46313 for a couple user confirmations).
Included is a log with +relay leading up to the crash. You can use grep -v 'GetLastError' to make it easier to read. As you can see, we're in the middle of a bunch of opengl calls.
One thing that stands out to me are the glDrawElements calls: opengl32.glDrawElements(00000005,000004db,00001403,00000000) ret=1403b751c
This does not seem to be valid usage of glDrawElements -- the last argument is intended to be a pointer to vertex indices: https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glDrawElements.xht...
Repro steps, starting from fresh wineprefix on intel graphics hardware: * winetricks dotnet35sp1 * Download/extract nirsoft RunWithProcess * wine ZwiftLauncher.exe, wait for any updates to finish * wine path/to/RunWithProcess.exe ZwiftLauncher.exe ZwiftApp.exe
