Subject Re: [libreoffice-users] ”Artifacts” in OpenOffice and LibreOffice
Date Sat, 11 May 2013 14:08:22 GMT

I have had subtle redraw issues with OO off and on, and I always blamed 
it on an interaction between applications and the video drivers. Realize 
that I use nVidia video cards on 64-bit Fedora using the proprietary 
video drivers. What I saw was not remotely as bad. Admittedly, when I 
tried out the latest dev build, it was totally unusable (of course, the 
single tester was unable to reproduce on Windows 7).

see https://issues.apache.org/ooo/show_bug.cgi?id=122214

Are you able to do a test and change your video driver say between the 
free and not free driver to see if there is a change (I do not use 
Ubuntu so I don't have a good handle on what drivers are available or how).

I used to have exactly the same problem in QT, and it was very bad. I 
was able to avoid the problem with QT Creator by starting it using

-graphicssystem raster

Not that I expect this to help you. I did notice that it still has some 
rendering issues that appeared in the latest versions (I believe it is 
related to an over-lay issue when you edit a field.... that assumption 
allowed me to fix it in the software that I write, but I did not jump 
into the QT code base).

I have seen strange redraw issues so long in OO that correcting for it 
is almost automatic in my brain (scroll screen up then down to clear) so 
I cannot even say if I still see the problem. I think I do, but it is 
for sure not as bad is it used to be for me.

I know, that I have rambled on and on.... I will summarize in saying

1. I have never seen it so bad
2. I have seen screen corruption
3. You may avoid some of it based on the video driver

If I had it that bad on my Fedora system, I would likely change my 
desktop on login to see if it helped. With Fedora, I can easily jump 
between Gnome and KDE (as one example). I would also try jumping between 
the two different drivers available to see how that helped as well. 
Sadly, the "free" driver is poor with respect to 3D stuff.
