I have this problem also. Also the workaround works (but slows things down somewhat). This particularly effects terminal windows and dialogs (or maybe I just notice it in those more because they open and close more, and in the case of dialogs, are unsizable and thus unrecoverable).
My hardware is an i910, using the latest xorg (1:7.1.0-5) and compiz (0.2.0-1). -- -><- Nick Rusnov -><- http://nick.industrialmeats.com -><- [EMAIL PROTECTED]/[EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
