I have an issue certain applications not displaying the scroll bars
I am using the upstream Nightly version of Firefox and the upstream
Daily version of Thunderbird. Both of these display the vertical
scroll bar permanently, but neither of them display the top and
bottom arrows. Another application I have looked at is Gedit which
only displays the vertical scroll bar when you mouse over it, but it
doesn't display the top and bottom arrows either. I get these issues
irrespective of what KDE theme I use.
Looking at the KDE Settings App it displays the scroll bars with top
and bottom arrows fine.
The Kwin script to force window decorations on GTK+ apps is active.
Does anyone have any ideas why the above mentioned applications don't
show the arrows but the KDE Settings Application does show the
arrows, and whether or not there is anyway to rectify it? From memory
I did not have this issue in F21 and F22 was installed from scratch
from the live DVD because the F21->F22 upgrade process does not work
on my system (the upgrade process wants to run the install from the
Grub menu and on my system my wireless network is not active at that
point and cannot be made active because of required drivers).
About scrollbars, gedit is gtk+ application (gtk+3.x in this case), not
sure about FF and Tbird (nightly builds could use gtk+3.x), Fedora FF
package uses gtk+3 now, so editing theme or changing it can give you
arrows, and about hidden scroll bars it is a new gtk+ feature
(>=3.16), so one way is to change default GTK+ theme, or possible
solution is to export "GTK_OVERLAY_SCROLLING=0".
