it seems like Mesa doesn't handle this situation right: dolphin creats the Context on one thread and makes the context current on another one. with DRI2 you get a white window and with DRI3 mesa simply crashes.

Doesn't seem like Intel backend issue. What's the correct component for EGL context handling issues, EGL or "Mesa core"? The crash should be resolved with the following commit. Feel free to reopen if that's not the case. commit d98d6e6269167230d20efdc45d608435a52f25fb Author: Dave Airlie <airlied@gmail.com> Date: Mon May 30 08:02:00 2016 +1000 egl/dri3: don't crash on no context.

Created attachment 122904 [details] Stack trace of the crash When Dolphin-emu is compiled with EGL (-DUSE_EGL=ON), and set to single core mode (Config > General > Enable Dual Core disabled), it crashes in egl_dri3_get_dri_context(). This doesn’t happen in dual core mode (where the emulated GPU is running on a different thread than the emulated CPU), or when Dolphin is compiled with GLX as its context API, but it happens on both Xorg and Xwayland since both are using DRI3.
