Fixed by commit 22e03954608e87d5ff1c6be11605d072cb1ab2dd Author: Kelly Ledford <stripes416@gmail.com> Date: Fri Mar 3 18:03:30 2017 -0800 x11-base/xorg-server: Warn about performance with USE="wayland -glamor" |
When xorg-server is installed with wayland support but no glamor support, xwayland will work, but programs needing 3d acceleration will be extremely slow because they are stuck using swrast/llvmpipe instead of a hardware driver. This can be very hard to diagnose, and there's not much information online to help anyone having this problem. I recommend we put a warning in the ebuild when someone installs xorg-server with USE="wayland -glamor". Something like the following: pkg_setup() { if use wayland && ! use glamor; then ewarn "Without glamor, 3d acceleration in xwayland sessions may be slow!" fi }
