Citra only gets a GL 3.0 context on GDK_BACKEND=wayland

[linkmauve]

Citra asks for a core 3.3 context, and gets a 3.0 context instead.

See the context creation code here: https://github.com/citra-emu/citra/blob/master/src/citra_qt/bootmanager.cpp#L264

Thanks for the report. Is there some kind of a way I can test this easily? I am not at all involved in emulation.

You can use any homebrew with Citra, most of them are free software, such as this one (which includes a pre-built binary): https://smealum.github.io/3dscraft/

Download it, unzip it, build Citra, then run citra-qt 3ds/3dscraft/3dscraft.3dsx.

Thanks, that worked. @special, any ideas?

Well, turns out we're ignoring the surface format's version entirely for wayland contexts. So uh, that's why.

Will get this fixed later today.
