screen flicker when copying files

I have the same problem. Hope it will be fixed.

I've been having this issue...was wondering if it had anything to do with the graphics card. I'm running a Mid 2011 MacBook Pro with a switching Intel HD 3000 / Raedon HD 6750M. I wonder if it has anything to do with the graphics card switching for that task, perhaps? Glad and sorry I'm not the only one!

I've been having the same issue on both a work system which is a Mid 2010 Dual Quad-Core Mac pro with a GeForce GT 120 graphics card and new 2011 home system which is a 2X6 Core Mac Pro with dual Radeon 5770 cards.. so doubt it's graphics cards as that's 3 different cards all having the same issues. Mine seems to primarily be when copying to my desktop. Always get the flicker as drag over desktop from folder just before dropping.

I'm seeing the a weird black /white flicker when dragging files down towards the dock. It only started after updating lion from the initial 10.7 to the latest update. I'm in a mid 2010 MBP. I also had just updated that MBP video update around the same time. Seems to happen pretty consistently.

Same here. Happens when a file is dragged from e.g. Downloads and is hovering over the desktop. Mid 2011 MacBook Pro.

Mid 2011 27inch iMac with AMD Radeon HD 6970M 2048 MB belongs here too :-(

I'm having the same issue here. Only noticed it when I upgraded to Lion. Any way to resolve this? or I just go back to Snow Leopard...

*bump*

Same problem:

27" Mid 2010 iMac

2.8 GHz Intel Core i5

ATI Radeon HD5750 1024mb

Mac OS X Lion 10.7.2 (11C74)

I mainly notice it when I drag and drop a file from my "Downloads" stack in my dock to the Trash icon in my dock.

Has anyone had any luck finding a solution for this?

I purchased a macbook pro 13" last week for my staff and it had lion on it. Same problem when drag and drop.. but this time the icon got stuck on the desktop and only a reboot made it go away. It is obviously a Lion issue. what perturbs me why did apple release a buggy OS? apparently lion 10.7.3 might address this issue but this should be tackled in the development stage!!! matter of fact snow leopard is still the best. I'm sorry for those who do not have the option revert (NOT downgrade) back to it.

Just noticed this glitch after performing a combo 10.7.3 update on my mid 2010 MBA. No issues on my mid 2011 mini. I noticed that this flicker when dragging files over the desktop only occurs when in native resolution. Lower the screen resolution (looks crappy)....but flicker is gone. Thought about reverting to 10.7.2 (maybe it existed, but I never noticed??) or even backtracking to Snow Leopard (excellent OS). Not looking forward to the exercise, I decided to sleep on it. Here's what fixed it for me: switched to an Apple built in desktop background. Not sure if it's the size of my custom photos or what, but switching to an Apple desktop image works!!

Apple really should respond more in these forums. This sort of thing could drive a person insane trying to determine if it's software, hardware, or.....

noticed this issue after upgrading to 10.7.3

typically it happens when I'm dragging some file from Finder window opened on a network share to a desktop.

That is some weird flickering - like a graphics card memory is getting filled with some random garbage. Weird it's not fixed yet! Apple that's a shame.

This has nothing to do with the desktop image. I just got my new MacBook Pro 17" 2.5Ghz 3 days ago - latest model - Radeon 6770 and intel 3000. Background image is the "original" one.

Screen only flickering sometimes when dragging a file to a folder on desktop, but having a flickering file icon of some sort down in left corner every single time i drag a file to a desktop folder.

This must be some sort of OS flaw with 10.7.3. Looking forward to a patch since it gives the impression that the OS is unstable/flawed.

*BUMP*

i have a 13" Macbook Pro 5,5 (2.53 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR, NVIDIA GeForce 9400M 256 MB, Mac OS X Lion 10.7.3 (11D50)) and have the same problem. It happens during the animation of the icon as it switches its orientation, format, etc. This is a new feature of Finder and apparently they have bugs in the graphics accelleration code (my Mac is one of those with noisey GPUs where you can hear high pitched noises from the left beneath the keyboard). The animation doesn't make much sense sometimes because the text wrapping changes depending on where the icon is placed. In fact, sometimes the animation is pointless because the icon changes into the same thing it was already. The glitches look like video buffer junk (small multi-colored rectangles with maybe ASCII-like junk?? it's too fast to really see) and flashes of the icons already on the desktop (flashing randomly around on the desktop) and the one being dragged. It's quite distracting.

EDIT: i just upgraded to Lion a couple days ago. Never had problems with Snow Leopard.

(you gotta be kidding me... this forum disables default Safari context menus and spell check? this is the APPLE forum, so you'd think it would behave with Safari)

Message was edited: added detail.

I am having the same troubles here too. It was happening before I updated to 10.7.3 but for some reason it stopped. But now after the update to 10.7.3 it is happening again. Weird though, it's only happening on one of my two monitors, the one that is hooked up by dvi. The other monitor is vga to mini display port and does not have any flickering when dropping files onto the desktop. I may need to buy a dvi to mini display port adaptor and try that out.

Yes, I've also seen the same kind of flicker since upgrading to Lion when dragging a file from an open Finder window to the Desktop

Only started using Lion 10.7.3 last week booting from a separate internal disk. Never saw this happen using 10.6.x on the same machine:

• Mac Pro
• 2.66 GHx Quad-Core Intel Xeon
• NVIDIA GeForce GT 120 512 MB

That is some weird flickering - like a graphics card memory is getting filled with some random garbage.

Wondering if having VMWare Fusion 4.1.1 installed has anything to do with it
