Blue Screen (BSOD) when using Steam overlay for Steam Controller and GloSOC

Description

Both the current stable and nightly run fine when started outside of steam. But when starting Retroarch in fullscreen with GLoSOC ( https://github.com/Thracky/GloSC/releases/tag/2.0.8 ) to be able to use the Steam Controller (SC) as an xinput device as well as the Steam overlay to rebind controls, Retroarch blue screens (BSOD's) my PC.

I have tried turning off all overlays, including the GloSOC overlay (just runs as a way to present SC as xinput device) as well as AMD overlay and the Retroarch overlay and notifications.

Expected behavior

Retroarch in full screen should allow the Steam overlay so I can rebind controls on my Steam Controller. Steam Controller with GloSOC has always worked with all my other games and applications without any bluescreen problems.

Actual behavior

Retroarch is conflicting with something in the Steam Controller overlay in fullscreen. It also may be the way GloSOC is implemented that is causing a conflict.

Steps to reproduce the bug

1. Set Retroarch to start in full screen.
2. Create a GloSOC shortcut for Retroarch.
3. Start Retroarch using the GloSOC shortcut.
4. Bluyscreen (BSOD).

Bisect Results

I don't know if this bug is a new one as I have not tried older versions.

Version/Commit

You can find this information under Information/System Information

• RetroArch: 1.9.0

Will add nightly version number later.

Environment information

• OS: Windows 10

For developers/log.

I don't have my PC in front of me but will add a verbose log ASAP.

The Steam Controller overlay can be used with almost any Playstation, Xbox or generic controller so you don't have to own an actual Steam Controller to test.

Start with the reproduction steps in the issue and collect RetroArch's Information/System Information details, including the nightly version, plus the promised verbose log. Reproduce the BSOD with fullscreen RetroArch, GloSC, and the Steam Controller overlay; completion requires identifying the conflicting component and a verified fix or actionable diagnosis.
