Hi Edwin,

to see the old scrolling problem again is a bit surprising for me. I was
rather sure we did resolve it a long time ago.

Fedora 20 has been out for some time now, and this is the first reported
issue for it. Maybe we should try to rule out all other possibilities
that could have caused the issue.

Could you first make sure that you switch off any possible GNUstep
theme? If this solves the problem, recompile the theme and try again.

The next thing you should check is whether the cairo library that gets
used during compile time is the same as the one used at runtime. Maybe
you have an outdated cairo dev package somewhere?

After that you should run ldd on the GWorkspace executable and report
back the result. Is there any suspicious, old looking library in the list?

With all that ruled out, it is getting difficult. There could be some
disagreement between GNUstep and the window manager about the size of
the window decoration. You should run "xprop -root |grep GNUSTEP" and
report back the values and compare them to the actual values used for
window decorations. (The values are right, left, top, button for all the
16 different window styles) But judging from your screenshot you are
having GNUstep draw the window decoration, not the window manager.

That is about everything I can think of at the moment. Please feel free
to report anything you find out.
