MBP 13" Medio 2010 Lion - Graphics problem

Hi,

do you also have an 13" MBP from 2010? Or which model do you own?!

I can't answer your question - sorry.

Maybe 10.7.3 will fix it ;-)

Yes, I have a mid-2010 Macbook Pro 13" (2.4 GHz Core2Duo, 4 GB RAM, 500GB Hybrid SSD Seagate)

Hopefully it will be out soon :-)

I am having exactly this issue on a mid-2010 MBP with a Nvidia 320m GPU. Had been perfect under Snow Leopard, but glitches as pictured under Lion 10.7.2. We all hope 10.7.3 will fix it, but if it doesn't I'll be putting this machine permanently back on SL.

Hi,

anything new aboth the glitches at your macbooks?

I still get them sometimes. I hope 10.7.3 will arive soon!

Steve,

Yes, still getting them. I've tried eveything I can think of including:

1. Running Apple hardware tests that came on the Applications CD (no issue found)
2. Running Memtest86+ (no issue found)
3. PRAM reset (still glitches)
4. SMC reset (still glitches)
5. Reverting back to factory-installed RAM sticks (still glitches)
6. Installing smcFanControl making the lowest fan speed 3000 rpm (still glitches)
7. Reinstall 8GB Crucial RAM, remove smcFanControl, reset both PRAM and SMC (still glitches)

I've not found any particular pattern to it, neither a sure-fire way to reproduce it nor any way to avoid it. Every now and again, it just happens (once or twice during a full day of use).

I also had bugs like these. Tried this : http://www.youtube.com/watch?v=gmoWoeNrkOs

And finally it seems it works. No glitches since 2 days.

I wonder if Apple is even looking at the forums. I have seen at least 15 posts tonight about graphics issues with Lion, I have issues too. Apple seems to not care since 10.7.2 came out months ago.

If this is true, then it is likely that changes between graphics power management states are the root of the issue.

Disabling Apple Graphics Power Management completely as you have done, will probably mean that you generate more heat in the GPU and have a shorter battery life. I just hope that the extra GPU heat doesn't mean shorter hardware life as well...

Please report back if your glitches come back or if this looks to be a permananent fix.

No more glitches since I "disabled" the Apple Graphics Power Management file about one week ago. I cannot recognize a shorter battery life. (just have the nvidia 320m chip version). The cpu heat is also the same like before (about 50 degrees in idle mode , means just browsing and finder work).

So Apple please fix it!!

Good to know, thanks!

New CUDA driver for MAC OS are also out. Maybe this will fix this issue. I hope so! Give it a try!

Ok I have to say no!! Glitches appear with the new cuda driver.

Hi,

@ dsdreamer - did you try the fix? If yes, did it solve the glitches??

@ all - let's hope it will be fixed with 10.7.3. Hopefully it will be released in the near future ..

have the same problem. who already try this fix?
