XRandR allows to scale the outputs which is really useful on hidpi scenarios. In this cases the CRTC reported size is bigger than the modes actually being used, for example: eDP1 CRTC: 2560x1600 Mode: 2560x1600 HDMI1 CRTC: 3840x2160 Mode: 1920x1080 HDMI2 CRTC: 3840x2160 Mode: 1920x1080 That makes a total of 10240x2160 in CRTC size which is bigger than GL_MAX_VIEWPORT_DIMS, but actually the value of the modes is 6400 which is under the maximum reported (8k). Besides the warning, compositing works great, no black windows or artifacts of any kind. Reproducible: Always
can you please attach "xrandr -q" and "glxinfo -l"
