OSX Lion, Graphic Artifacts

I have two Macs; iMac i7 and MacBook Pro i7. Both came with Snow Leopard and worked perfectly. I download Lion for the Macbook Pro and lost Office and Parallels 6! Other problems included missing icons and lost my Address Book. No artifact or heating problems but I don't watch videos fromYoutube on the iMac. I reloaded Snow Leopard after removing the Lion - best thing I ever did was get a Buffalo 2tb time machine backup and let it do a constant monitor. I also have a 400Gb external drive for an Best Operating System image. That is, when you first get everything installed and before updating anything, take a snapshot of your drive, including system. Then if something goes wrong, you can revert to a 'last good system' and at least start from a working base. Lion is just plain trouble for now.

Hello. I have the same problem with artefacts. Upgrading to 10.7.1 didn't solve it.

No point in shouting "solve it" here, it's a user forum. Try sending proper information to Apple!

@Putnik i wasn't shouting "solve it". The image made "solve it" appear on another line. The full message is Upgrading to 10.7.1 didn't solve it.

Maybe with 10.7.2 the problem will be solved. There are users reporting sound problems also.

Sorry! That's another problem people have noticed, pasted images always seem to arrive inside the text... I find the cursor not nearly so responsive in Lion, it makes editing difficult and unhiding the dock infuriating.

I suggest you send a system log and the screenshot to:

Same problem here. I've reset the PRAM, run the Apple Harware test etc... nothing works

A full Lion reinstall (loaded by pressing Command-R at the apple boot sound after restarting) does the trick.

Before this I ran Apple Hardware Test, reset the PRAM, reset the SMC, and ran the system's Disk Utility software. These did not fix the problem.

As I posted in another thread regarding the graphics issues in Lion:

Lion has major bugs with both their video drivers and OpenGL. Because these drivers are running the GPU, some of the data in the PRAM and SMC become corrupt. There is no fix on this issue as of yet, and Apple knows about the issue, As far as the graphic artifact problem, that has to do more with the faulty OpenGL.

(A game developer received this information from Apple, so I trust my source)

Apple will never get OpenGL right. Poor developers manage to build game engines on it somehow, yet Apple themselves can't even make simple core animations smooth.

I hope I don't get silenced for disclosing this :\

I was told that the issue is 100% on Apple's end. The developers are powerless to fix this problem.

"(sorry for my english)"

NO need to apologise. It's perfect.

Thanks !

Concerning the artifacts issues, I fortunately didn't encounter it anymore, but a week ago I was faced with another issue. I left my Mac on (in order to take control with VNC) and go on vacation.

When I tried to connect to my Mac, I wasn't able to enter the screensaver password because the display was very sluggish. I though it was my DSL connection speed, so I closed VNC viewer.

I left my iMac "as it".

When I came back yesterday, the Mac was on, stuck on the "sluggish screensaver". The whole computer was very, very slow. But without display issues. I was able to reboot the computer, and everything was OK again...

I've just updated to 10.7.1. I am going to left my Mac on to see if the problem occurs again.

Interesting!!:

Apple replaced my new imac 27 3,4 i7 with this problem:

with a new one!

But the new one has still the same problem!!!! Weird!!!!

What should I do?

Let it be replaced again???
