[PATCH 0/1] MR8977: winex11: Use EGL by default for OpenGL rendering.

[Rémi Bernon (＠rbernon)]

When we were able to load it at least.

EGL has some advantages, like not requiring a specific pixel format on the windows, it will share most of its problems with winewayland (and wineandroid although we may also assume GL doesn't work anymore there at this point) so anything fixed with it could benefit all. It will also be required for shared resources and compositing when Vulkan is unavailable.

This might be a bit early still, I'm not sure it is on par when it comes to child window rendering synchronization. However this doesn't drop GLX either, and instead just changes the default. I think it would be useful to switch early though, at least to have more time to settle (and eventually decide to switch back during code freeze if it proves a bad idea).

[William Horvath (＠whrvt)]

I'm not sure if it's just some misconfiguration on my system, but X11 EGL doesn't seem to work at all when using XWayland from a Wayland session with proprietary NVIDIA drivers. It works when running in X11 natively, though.

Just something to note. It might only be an issue on my end.

[Rémi Bernon (＠rbernon)]

Thanks, I wasn't aware of that. Might be indeed some underlying compatibility issue, I'll try to reproduce.
