Why does Firefox display start OK, then resort to vertical lines?

more options

It started about a week ago - Firefox was displaying fine, but now if I am on (say) facebook and I start browsing downwards, after a while I get sentences degenerating into vertical lines (not unlike a bar code). Sometimes there are gaps.

Refreshing the page cures it, but the problem occurs again a little further down.

Explorer works fine - but I'd rather use Firefox. Can you help?

hello, maybe that's an issue with hardware acceleration - please try updating your graphics driver, or in case this doesn't solve the issue or there is no new version available at the moment, disable hardware acceleration in the firefox menu ≡ > options > advanced > general (that setting will take a restart of the browser to take effect).

I will check the graphics driver, but it was the second part of your email that seems to have worked.

Hardware acceleration was already disabled on my Firefox; so I enabled it and reloaded; then disabled it again and reloaded; so far, it looks to have cured the problem. Thanks!
