Details

Description:
Multiple applications (e.g. webview of Epiphany and email rendering of Evolution) just show a blank white surface instead of any content. No segfault is detected (neither in the webkit2gtk nor the host process) and no logs (kernel, application) exist that may give a useful hint.

The problem exists on Xorg as well as on Wayland.

Installed packages (all 64bit):
* intel-ucode 20161104-1
* libdrm 2.4.75-1
* linux 4.9.8-1
* mesa 13.0.4-1
* vulkan-intel 13.0.4-1
* webkit2gtk 2.14.4-1
* xf86-video-intel 1:2.99.917+753+g9fe04af4-1

Hardware:
* Intel® Core™ i5-5200U CPU @ 2.20GHz × 4
* Intel® HD Graphics 5500 (Broadwell GT2)
* 8GB RAM

Steps to reproduce:
1. open Epiphany
2. go to any website
3. see nothing :(

I confirm that the upstream bug reflects my scenario (HiDPI). The upstream bug was marked as solved, so I guess the "package bug" will be fixed in the next bugfix release of webkit. Thank you for your work! :)

I also ran into this today on a machine with a HiDPI display. Epiphany and, more importantly for me, Evolution are completely unusable at the moment. It would be really nice, if a new release of webkit2gtk incorporating the fix could be made pretty soon.

It is always a good feeling to find the bug you just ran into already reported (and even fixed) when you are just about to report it yourself. Great work, thank you all!

Actually, I can confirm that the patch from upstream indeed fixes this issue. I built it locally with the suggested change applied and web views get rendered again in both evolution and epiphany on my HiDPI machine.
