On host gx780 with TDE, I did a fresh zypper dup from 13.2 to 42.3 with favogt repo enabled. GTK3 RV54 and RV55 builds from mozilla.org *are* using the same UI text as other apps. IOW, good fix WRT UI fonts. 42.2 and TW do need this (and Firefox is still using scrollbars so narrow they are hard to see or target, ignoring "use my TDE style in GTK3 applications"). WRT cursor I can't recall seeing the problem described in comment 0. Should it not be a separate issue/bug?
