When there is background action, thunderbird (as many applications) shows a "busy" mouse cursor. It's usually an arrow with a watch or an hour glass, but of course this depends on the theme. Beginning with thunderbird-9.0, the mouse cursor theme is ignored and the default, ugly black cursor is shown instead. Mouse pointer theme for testing purposes: Pulse glass. This is a regression, it worked fine in thunderbird-8.0. Reproducible: Always Steps to Reproduce: 1. Check for new mail or do something else generating a background task. 2. Observe the cursor. Actual Results: The default ugly black X cursor is shown. Expected Results: The nice, themed cursor should be displayed.
are you only seeing this in mozilla products or other gtk2 products as well?
No, this is specific to thunderbird only. Other apps or firefox are not affected.

The patch v2 from https://bugzilla.mozilla.org/show_bug.cgi?id=709259 fixes the problem for me.

We have a new patchset rolled for the upcoming release, it will be fixed in tb/fx-10 which should be released later this week. Thanks for reporting.
Closing as this will migrate to tree with official release.
