r47 - 7626388b45d8bd87b2f78cd89f76b52e9116bf7c - slows down here message list scrolling (page up/down or using mouse) when message preview is disabled. With message preview "v" enabled scolling doesn't slow down here. Reverting that single commit (currently on top of r68) allows fast scrolling again.

Using Arch Linux here using cairo 1.17.4.

I am seeing the same with cairo 1.16.0 on fedora.

I'm seeing it on Windows as well.

It looks like the message view doesn't need to be hidden; if I shrink it down enough to let the message list take up most of the window I still see the slow scrolling.

You can also see it with the folder list if you resize it to take up most of the window.

Reverting 7626388b45d8bd87b2f78cd89f76b52e9116bf7c works fine on Windows with GTK3.

The original performance issue with updated cairo versions doesn't seem to be present with the GTK3 build.

7626388b45d8bd87b2f78cd89f76b52e9116bf7c now reverted in git.
