Screen tearing in full screen mode
Submitted by Prashant
When I go into full screen mode in evince and scroll in any file with lots of images (say a comic book), there is screen tearing. This appears to be on account of unredirect fullscreen windows feature of gnome-shell as installing the extension at https://github.com/kazysmaster/gnome-shell-extension-disable-unredirect (after updating its metadata.json to work with Gnome Shell 3.26) fixes the issue.
Please correct me if I am wrong about this but isn't the unredirect fullscreen windows facility meant for gaming? It seems to be applied, incorrectly IMHO, to Evince, resulting in screen tearing in full screen mode.
I am running Gnome 3.26 on Ubuntu 17.10 on Xorg with the modesetting driver.
