All EGL programs I could find, started to segfault in eglChooseConfig() on all Intel platforms between following Mesa commits: * 3de87f7cd7 at 2017-10-17 16:17:15 UTC vulkan/wsi: Free the event in x11_manage_fifo_queues() * f37af5ec8d at 2017-10-18 17:36:53 UTC st/mesa: set dimension for constants in ATI_fragment_shader There are several commits from Eric that change Mesa EGL code between that range. Backtrace to crash is following: ---------------------------------------- $ gdb glmark2-es2 ... (gdb) run Starting program: /usr/bin/glmark2-es2 [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
