Comment 1 Luya Tshimbalanga 2019-10-27 17:54:43 UTC

Upstream provided the patch on https://gitlab.gnome.org/GNOME/gtk/commit/e997ef60da5388e51e0d1afc2f72443a56c36037

It will e nice to back port it for the current release.

Comment 2 Luya Tshimbalanga 2019-11-07 03:27:12 UTC

Reading the bug report on https://gitlab.gnome.org/GNOME/gtk/issues/2157, it turned out the problem is on GTK3 when using scale-monitor-framebuffer to 125% on Wayland session. 
The fix is already available and it will be nice to get it on this release. Assigning the issue to GTK3 and referencing upstream report.
