I just realized Blender 2.47 was released, and after installing it on my MacBook running Leopard and noticing its slowness I wondered: are there any news on this known problem?
I recall finding some discussions about it some time ago, maybe for 2.45. It looked like this slowness (e.g. when drawing menus) was due to a bug in Apple’s graphic drivers or something like that, and someone released a custom built Blender version which worked around this bug.
Has any workaround been integrated into Blender in the meanwhile?
Or are there more recent custom builds available?
