[Bug 1448937] [NEW] LibreOffice has serious kerning issues with characters' display of font, bold, italic

 

Public bug reported:

I run in to distorted text in LibreOffice, depending on zoom level. At
first I thought it was a LO-bug, but now I have found that I don't get
this issues when I run the AMD proprietary driver (fglrx). So I think it
might be a problem in the xserver-xorg-video-ati driver. I have a Radeon
HD 8600M series in a Lenovo S540.

The attached file shows an example of the bug that I had in Calc. The
bottom right is the 'normal' text. Three lines, with the bottom one in
bold. Depending on the zoom level, the text is distorted in many ways:
bold / italic / font (appearance).

Some extra information:
-This happens in all LO-apps I use: Calc, Writer, Impress.
-I don't have a clear way of reproducing it. The apps normally start out perfectly fine. After a while this can happen, not always. Risk factors seem to include having multiple LO-files open, especially between different apps.
-It is not always that the 100% zoom level is ok. That can be distorted too.
-This never ever happens in any other app / program I use.

If this is unlikely to be caused by the xserver-xorg-video-ati driver, I
apologize for reporting it here. If you need additional information,
please let me know, I will be happy to provide.

Required info:
1) Ubuntu 14.04.2 LTS
2) xserver-xorg-video-ati Installed: 1:7.3.0-1ubuntu3.1
