P: brush cursors not working on 2011 Mac/MacBook Air (OS X 10.7.x Lion)

the 'genius people' are useless- last time when I was investigating whether it would be possible to 'downgrade' back to SL (in my opinion rather an upgrade, experiencing the mess in Lion) with my new MBA 2011, they had no clue that there might be issues of missing drivers for thunderbolt etc..., so yes, scratch this idea- we are stuck with beautiful Lion!

Yes, Apple can fix it with a software update. But the bug is somewhere inside their video drivers, and we can't fix it from the application side.

Well scratch that idea. Apparently the new Macbook Air's require Lion to support the hardware. This is really frustrating! If it is truly an OS compatibility issue, can't a software update fix it?

Now I'm a bit confused. I took it into the Apple Store today and reported the issue with them at the Genius Bar. They seem to think it is an issue with compatibility with Lion rather than their hardware drivers. Could this actually be the case? I'd consider this good news because I have no problem wiping this thing out and downgrading to Snow Leopard. I'm not going to do it if it will be a waste of time though. What do you think?

Photoshop and Lightroom use the Cocoa APIs, but not exactly the same code for cursors. Yeah, this is a video driver bug. There's no way both programs would have the same bug.

Apple is sometimes quick, and sometimes not. The more customers tell Apple about the problem and ask for a fix, the higher priority they'll put on it.

Is Apple quick about fixing this sort of thing? I just got the new Air and I love it other than this issue but it will really hinder my design work not being able to use brushes.

I too suspected the video card driver but the brush in Illustrator works fine. In LR and PS, the ouline of the brush tip stays the same for a range of sizes, resulting in an diagonal offset of the painted stroke to the outline.

Exactly Chris. The brush cursor just disappears at different sizes. I hope they hurry because it isn't usable as is.

So it's just not displaying the cursor correctly? Ok, that's a bug in the video card driver, and Apple will have to fix the driver. Hopefully that's specific to the MacBook Air.

same here- with both, LR3 and PS CS5 on a MBA 2011 (11"). Is it Lion or anything MBA specific?? No clue. I un-/ re-istalled various apps, activated/ deactivated preferences related to display resolution, trackpad, mouse, pointer etc. without any success of changing the brush behaviour back to normal.
Without having the chance to reinstall the whole OS- I wait for the USB-stick version of Lion- I feel stuck...
