Description Jaak Ristioja 2007-05-19 20:14:10 UTC
On some pages (for example the estonian news site firefox has trouble displaying some titles. It only displays the first word on every line of a title. After repainting those regions it might display them properly, but even after these regions appear, they might be corrupted by windows moving by (exposure). This happened some time after upgrading cairo and some other stuff like that.

This is how the page looks after being displayed the first time.

Notice the titles of the news articles in large bold letters.

After redisplaying the page.

This is how the page looks after minimizing and restoring the firefox window. Just starting KSnapShot has the same effect - firefox repaints its window.

Again, notice the titles. I moved the KSnapShot window over the titles in the bottom and center of the screenshot. This resulted the corruption. Also observe the thumbnail in the KSnapShot window which was taken on KSnapShot startup.

I had similar problems on my ppc machine and seamonkey, on some websites ( was one of them). The text was complete everywhere, but the colors were distorted.
The problem was solved by downgrading to cairo-1.4.4.
Comment 4 Jaak Ristioja 2007-09-25 14:08:42 UTC
Hmm... I forgot I had this one filed here... anyway, I'm long using newer versions of Cairo and Firefox (1.4.10 and, and I haven't encountered the issue since.

Closing then
Comment 6 Jaak Ristioja 2008-06-05 19:14:25 UTC
The issue hasn't occured since, must have been fixed or been a random clitch. Closing.
