Leave clock running for about 1 minute - the hands render wrongly then the whole clock disappears. I'm running GtkLauncher using webkit 34798 on gtk etc on x11 on a Fedora 8 Linux PC. It runs fine (i.e. as expected) in Safari 3.1.2 (525.21) on a Windows PC.
No problems with build 34833 here. Looks the same like in Safari.
I tested it again on 34833 checked out from subversion and the clock still disappears after a minute or so. What system did you test it on? gtk? Fedora? It would be useful to perhaps locate differences in the build to see where a problem may lie. I built it using autogen.sh and make. Could it be a difference in cairo / gtk etc versions on the platform?
I build it with ./autogen.sh --with-http-backend=soup and libsoup from svn on ubuntu (WebKitGtk). I don't believe, that it is a problem of curl/soup, but I don't know. Which version of cairo do you use? It's 1.6.0 for me.
On the Fedora 8 platform it is cairo 1.4.14, pixman 0.9.6, gtk+ 2.12.8 (running on X), and on a different platform which takes between 6 and 24 hours to go wrong (rather than minutes) which uses cairo 1.6.4, pixman 1.0.0 and gtk+ 2.12.9 (running on DFB). Ok so looks like there has been an improvement in cairo or gtk but not a total fix. I shall upgrade my PC to use a later fedora core as it looks like cairo 1.6.x etc is not being released for core 8, and then test again.
Sorry for the lack of progress update on this, I've failed to upgrade my PC to use the latest cairo for various reasons and its unlikely to happen before I leave this job, so best to close this bug and if someone else finds it later, to reopen / create a new one.
This bug is hopefully fixed in newer cairo versions. I can't reproduce the bugs and no one else seems to have this problem. Closing the bug now.
