Ubuntu 12.10 Firefox 18.0.2 - text display is being over-written by smudges of colour and grey

Posted

I have an intermittent problem that text displayed on a web-page is over-written by grey and sometimes coloured smudges and lines that prevent the text from being read. The smudges and lines can diappear dependuing on movement of the mouse, but they also come back again with further movement.

For example, this problem occurred when I followed the instructions for installing the Troubleshooter add-on.

I also have several problems with Firefox 18.0.2 freezing when running on Ubuntu 12.10.

I've had a similar problem with 18.0.2 on windows 7 home premium 64 bit. See the text in the areas circled. If I scroll the text off the screen then back or highlight the text it usually clears up, but will randomly deteriorate again.

Edit: I just upgraded to 19.0 and the problem persists.

If you are on Windows then try to disable hardware acceleration.


On Linux hardware acceleration usually doesn't work.

(gfx.direct2d.disabled doesn't exist on Linux)
