Problem is fixed in Fedora's eclipse, which is now using GTK3 --
Problem is not fixed in all other applications that are based on the eclipse
framework, if they still use GTK2.
This is the case for a customized Eclipse LUNA environment, as well as for
IBM Lotus Notes 9.0.1. These applications worked fine in Fedora 20 and
their scrolling is broken since I upgraded to Fedora 22.
Luna has GTK3 support too so you can try switching your additional products to
It seems that the upgrade to Fedora 22 either broke GTK2 or introduced a
compatibility issue between KDE Plasma 5, Eclipse's use of SWT, and GTK.
What else could I try to narrow down the issue for these apps?
GTK 2 support is only going to become worse not better thus migrating to GTK 3
is the only path that makes sense nowadays.
As I understand, Redhat does not have the resources to address GTK2 related
issues, so users of Eclipse applications that have not yet been ported to
GTK3 are left in the rain ...
You're correct that we barely have the resources for the GTK 3 version but on
the other side GTK3 support has been in Luna and even rudimentary one in Kepler
so it's not like we haven't put significant effort into providing as smooth
path as possible for even older products.
