Since I installed Tumbleweed on my old HP laptop I have been having sever problems with LO writer: in short, it garbles and mangles text at every insert or delete operation (that is to say, always), and scrolling always leaves behind blank pages or even VERTICALLY deleted lines (ie, only the bottom half of the characters in the line are showing). i have to scroll repeatedly and/or select text in order for my text to reappear/get ungarbled.
I do not have this problem with any other application.
After intense googling, I saw the same problem reported for setups with NVIDIA cards. The usual workraounds are
turn off hardware acceleration in LO
turn off compositing effects in the WM
but they do not work in my case. My setup is as follows:
GeForce 8400M GS
2D driver: nouveau
3D driver: nouveau Gallium (8.0.4)
Linux 3.6.5-10-desktop x86_64
LibreOffice 3.5.413
