Besides some glitches in the VM, no visual artifact was noticed, in particular no glitch in the outer desktop (the VM was not fullscreen). The VM is a Fedora Rawhide, using the qxl driver (in case it matters). gnome-boxes was built from jhbuild, using mesa 7577cdd8300068bdf1eda426951d7141450283aa (+ my DRM-swrast patches, but they are not in the rawhide VM and they don't touch GLX or the intel driver, so they shouldn't matter here) and e8c3c1358ecaf4e90f7d43762357ae6f8e2022b6 The outer X was xorg-x11-server-Xorg-1.14.4-9.fc20.x86_64 (Fedora 20) + xorg-x11-drv-intel-2.21.15-5.fc20.x86_64, with SNA enabled. Kernel is 3.14.6-200.fc20.x86_64. This is a GM45 card.
