Description Frank 2018-01-07 14:54:55 UTC
Although in your Bugzillaa it is mentioned that bugs for Intel HD graphics should be reported to i965, my dmesg just shows i915, so I’ll report here. I own a Dell XPS 15 9550 and an “Intel® Core™ i7-6700HQ CPU @ 2.60GHz × 8” with “Intel® HD Graphics 530 (Skylake GT2) / NV117”. I use Fedora 27 with Wayland and have a mixed-dpi setup (UHD & HD screens). Mesa version is 17.2.4.

The bug is occurring by usage of the application Lollypop (via Flatpak), see my bug report there:

Lollypop crashes reproducibly when I open this mentioned widget, close it and want to open it once again (I added a screencast there). The author was able to reproduce it, added a backtrace and asked me to open a bug report here. I don’t have any idea about the graphics stack and hope that this is somewhat self-explaining… :/
