Reported 2009-11-25 07:12:08 PST
When loading a Google maps page, many of the buttons in the map view are shifted around and/or not working. For instance, the street view puppet is not usable, and even disappears from the screen. This only occurs with the recent nightly builds since about 2 weeks. The regualr Safari 4.0.4 does not do this and Google maps works as expected.

I can confirm this bug on a PowerPC machine too. This bug has been introduced recently, and apparently it seems to happen when JIT is disabled (which is obviously the case on PPC architecture). The bug can also be reproduced on x86 when JIT is disabled.
