Just posting this to see if anyone else is noticing what I have. I installed the Safari upgrade last night - and am noticing an intermittent graphic glitch. It can happen periodically - when either cmd-T - to open a new Tab, or cmd-W - closing that tab. It can also occur at other less predictable times - but the new tab function is easiest to consistently replicate.  This happens on both my 2011 MBP and my 2011 iMac - since upgrading to 5.1 yesterday.  It's a very annoying glitch.


You can see a video of that glitch here - reenRecording.mp4

    Try turning off your router for a few minutes then turn it back on. Restart the Macs. Try Safari.

    I'm having the exact same problem, Brian.


    This is actually something I had been noticing for some time before Safari 5.1. A short, graphics glitch when switching/closing tabs or CMD-tabbing from another app to Safari.

    Because it happened intermittently, seemed to be restricted to Safari's webpage area (didn't seem to affect the menu and tool bars) and the rendering would immediately get back to normal, I didn't worry too much about it.

    But now it's become impossible to use Safari at times!

    Not only are the glitches happening more often, but they won't go away once they start happening. Closing the tab and/or reloading the webpage won't work. I have to quit Safari and launch it again.


    Imagine the glitch in your video staying on-screen and flashing like an old ZX Spectrum game as I move the cursor. That's what I'm experiencing. I tried taking a couple of screenshots with Grab, but they come up blank. Whatever it is, Grab can't capture it.

    And here's the funny thing: just now, this started happening when I opened a page in this forum (this very thread, actually). I disabled Flash, Java and JavaScript, reloaded the page and it went away. I re-enabled them one at a time and the glitch only came back with JavaScript.

    I tried a different website with Flash banners and the glitch would come back if I re-enabled Flash + JavaScript, but not JavaScript alone. Weird.

    It seems there is a clear issue with Flash and Java/Script in Safari 5.1. Unfortunately, it's not the only issue with this release of Safari (I too am experiencing the font issues people have been complaining about).

    I was wondering if this graphics glitch was hardware-related - I've got a white MacBook Core 2 Duo with an Intel GMA X3100 graphics chipset and I'm running Snow Leopard 10.6.8 -, but you're seeing it in two completely different machines. Together with all the other issues people have been experiencing, it makes me think this release of Safari is simply buggy.

    I'm really disappointed with Safari 5.1 and hope they identify and fix these issues (or provide a user fix) soon.

    I have this issue on a MacBook. Sometimes the whole window goes blocky and the only option is to restart the browser. I tried to make a screengrab of this issue, but the screengrab when this happens shows as transparent!

    glitch (1).jpg

    same problem with my latest update 5.1


    none of the above hints fixes the issue.


    once i had a gpu malfunction that glitches were found all over the system, when the graphic unit was in use (instead of the cpu graphics)... and the screen froze and the system crashed.


    the new mainboard is still running well and i dont think the gpu is the reason for the safari new tab glitch issue i have now.


    sometimes beachball for no reason (no mouse action)

    disapears when clicking.


    i guess some threads are not working together nicely.


    bugreport on.

    its def. a gpu artifact, which shows visual fragments of the last website, photo or movie i opened.

    emptying cache and resetting doesnt help.

    manually deleting the acc. plists and , also completely deleting my safari and downloading new 5.1 and installed... didnt fix this.


    will this be fixed in 5.1.1 for snowleopard 10.6.8 ?


    safari browsing was never this backflashizzle

    here finally I've found someone else with my same issue !


    I've had the same problem with my IMac 2010 whit Snow Leopard 10.6.8, since the last update of Safari to 5.1.


    I've tried the same: emptying caches and cookies, delete the different, but nothing has changed...


    This last update has not been so satisfactory...hope Apple will be able to solve.

    Thank You

    yep - I have been experiencing this after upgrading to 5.1


    Latest iMac 27" Snow Leopard 10.6.8


    I thought I was going insane.


    What a strange bug to have let loose in such an advanced product!


    hope fix comes soon.

    The glitches will be gone when you upgrade to Lion. 100%

    No fix through Safari Updates. Only the upgrade to Lion solves it.

    I'm sorry but Lion didn't actually fix that problem, I have lion running on a Late 2011 iMac 27" and I still am getting the glitch every so often. Maybe Mountain Lion fixes it.
