Red Hat Bugzilla – Bug 248986
Very slow screen redraw/repaint during basic usage
Last modified: 2007-11-30 17:12:10 EST
We recently updated from FC6 to F7 and the performance of Open Office has fallen
significantly. All functions are good, but screen redraws when moving around
documents, or switching away and then back to an Open Office application, are
The screen redraws toolbar icon by toolbar icon.
When using calc, scrolling around involves painful redraws of column data, and
then selections. Sometimes in calc, selections are redrawn in an endless loop,
for a strobing effect, whilst there is no user interaction with calc.

Is this something to do with Cairo?
It shouldn't be cairo, cairo is used for the full-screen presentation mode, but
otherwise the UI stuff is effectively unchanged from FC-6. I haven't had any
reports specifically like this before.
Is OOo the only application that behaves like this ? And is there anything
unusual about your setup that you are aware of ?
btw, what desktop environment KDE or GNOME. Any particular theme ?
Thanks for following up. Desktop is Gnome, using the default Gnome theme
(Clearlooks I think it's called).
But, the problem that I raised in this bug has gone away. I don't have any idea
what resolved it. Happy for you to close it.
It just stopped redrawing horribly slowing and became acceptable recently ?
Perhaps there was some background process which was beating the hell out of the
I don't use OpenOffice every day, so I cannot put my finger on when things
improved, but yes the redraw problem was present from at least 18-Jul to 21-Jul.
I did check load, I/O, etc and there was nothing unusual. I also waited a few
days before filing the bug report. I really don't know what was the cause.
Maybe it was something in the xen testing kernel that I am using.
Sorry if I have wasted your time. I will keep an eye on it, and add a comment
if I see the problem again.
Most odd. Indeed, keep an eye on it and if there is something that triggers this
again reopen and we'll make a stab at figuring it out.
