Also there is currently no codepath that creates a GLES context in Xwayland, there is only EGL_OPENGL_API: https://cgit.freedesktop.org/xorg/xserver/tree/hw/xwayland/xwayland-glamor-gbm.c#n789 On the other hand, "standalone" glamor has a corresponding codepath for it: https://github.com/mirror/xserver/blob/9d628ee5facf6318368d5b8ca181e083adcffe8c/glamor/glamor_egl.c#L957 But this is only triggered if there is no Desktop GL available at all on the platform. I tried earlier today to switch the init in xwayland-glamor-gbm.c to use EGL_OPENGL_ES_API but then I had severe rendering errors on etnaviv with most text and icons missing. BTW in parallel this patch was posted to mesa today to downgrade GLSL to 120 as well: https://lists.freedesktop.org/archives/mesa-dev/2018-May/195060.html Thanks for merging!
