Also expected. WebRender uses GL_EXT_debug_marker to collect GPU profiles which isn't implemented by Mesa. $ MESA_EXTENSION_OVERRIDE=+GL_EXT_debug_marker glxgears Mesa 18.3.0 implementation error: Trying to enable unknown extension: GL_EXT_debug_marker Please report at https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa ^C https://github.com/servo/webrender/blob/7c4162c58197/webrender/src/renderer.rs#L1969 https://feedback.wildfiregames.com/report/opengl/feature/GL_EXT_debug_marker
