Description Adam Williamson 2016-11-16 21:23:13 UTC 
I just upgraded my laptop from Fedora 24 to Fedora 25 and switched to using the GNOME Wayland session.

The laptop has a 1920x1080 13" screen, so I set a text scaling factor of 1.3 in gnome-tweak-tool, to make text look about the 'right' size. However, it seems like under Wayland, the Evolution plain text composer does not respect this. I have not checked the HTML composer.

I have Evo configured with 'Use the same fonts as other applications' checked. Most of Evo does respect the scaling factor - the chrome and displayed emails (including plain-text ones using the fixed-width font) and so on. But when I compose a new email, the text is tiny, it looks like it has a 1.0 scaling factor.

Will attach a screenshot.

actually probably a dupe of 774248 .

mcatanzaro says in fact it might not be:

"I bet Evolution and gedit are actually different bugs with the same symptom. WebKit requires applications compute text size manually based on the size of the monitor and pixel density. I wish I were kidding, but we just copy/paste the same 100 lines of code to do this among a bunch of different GNOME apps; each new app that uses WebKit doesn't know to do this and is broken until we figure it out, and it's easier to copy/paste than spend a day fixing WebKit and writing layout tests for it. You might want to file an Evolution bug pointing at https://bugs.webkit.org/show_bug.cgi?id=142673#c6 "

so, re-opening this. Please see the above link.

We use the same workaround.. I'm tempted to close this, but I will wait until I talk with Michael..

Adam, did the 3.22.2 resolved your issues?
Comment 5 Adam Williamson 2016-12-01 16:48:03 UTC 
After a dnf update and reboot, gedit is still bad but Evo appears to be OK.
