Confirmed. Use either wayland or wayland-egl if you run a desktop under a Wayland compositor. I wonder why the assert message isn't displayed... This is the ASSERT: RELEASE_ASSERT_WITH_MESSAGE(backend, "EGL initialization failed"); 1533914 3 ludovico.denittis 2019-05-07 08:00:46 -0700 Yesterday I wrote a comment but probably got lost, strange. Anyway Philippe I also tested the "--platform wayland-egl" and I can confirm that it works. 1533915 4 pnormand 2019-05-07 08:18:31 -0700 Alright, let's close this then :)
