Description _ rkubacki 2004-03-05 19:24:45 UTC

When mouse enters tabs area we do check for
rollover effect and mark only one tab for
repainting. But on Win/OSX we then ask for
repainting of whole tabs visible area as these
platform return true from
wantRepaintOnGeneralMouseEnterExit(). A bit of
excessive computing. According to Tim it should
happen only on OSX and probably in better
optimized way.

While the overhead of this is very likely trivial (since if the user is moving the mouse, by 
definition the IDE doesn't really have a lot to do that the user needs urgently other 
than the tabs displaying correctly), on principle this should be fixed (plus it's overriding 
one method to always return false).

Setting initial target to promo D, priority to p4 (because the mouse entering the tab area 
doesn't fall in the critical path of, well, anything).

This issue was solved long time ago. Because nobody has reopened it neither
added comments, we are verifying/closing it now. 
If you are still able to reproduce the problem, please reopen. Thanks in advance.
