The mail content in Geary is displayed blurry on my HiDPI display, as are websites in Midori.
After some research I think using the latest WebKit version could fix that.
I found this info about how to compile Midori with the latest WebKit version, but libwebkit2gtk-4.0-dev does not seem to be in the repos and I am not certain about how to adapt the steps described therein for use with Geary.
Any help or info would be much appreciated.
No need to compile anything: you can just update to a newer libwebkitgtk - then Geary (and other applications like e.g. the WiFi login window) will use that instead of the old one. I think the issue was fixed in 2.4.9, but the version currently available in the repository is 2.4.8.
sudo add-apt-repository ppa:webkit-team/ppa
sudo sed -i s/trusty/vivid/g /etc/apt/sources.list.d/webkit-team-ppa-trusty.list
sudo apt-get update
sudo apt-get install libwebkitgtk-1.0-0 libwebkitgtk-3.0-0
Don't blame me if that breaks things - I destroyed a lot while finding the solution!
Edit: fixed a lot of wrong things about this :D
It's not currently possible to build Geary with WebKit2. You would have to branch the source code and manually port it (not a trivial task and not something it's possible to list steps for).
