Possible Graphics card glitch?

[RyanWW]

Anybody got any idea what this is?
A while back i did spill drink on my Macbook Pro but I took it to an apple store and they said while it was damaged if it works okay it's not worth spending the money to repair it yet, which i thought made sense.
Could this be to do with that? or would this be unusual? I hear some people say generally if you spill liquid on a computer whatever damage is done at the time is just that, it doesn't get any worse over time, it'll just be as bad as you made it

Thanks Guy's

If it is just the dock experiencing that try opening Terminal and typing "killall Dock" without the quotes and hit enter. It'll kill the dock process, but will automatically relaunch on its own. If that doesn't fix the issue then I would say it's graphics card. You can also see if moving the dock to the bottom or right side of the screen helps. It might be having issues drawing on the left and be unrelated to the dock.

That did actually work, thanks a bunch, what would cause this though?

Also, while I have this thread it might be worth asking is there any particular reason my macbook would keep crashing in clamshell mode?
it's not all the time but it seems every other day i'll leave it to sleep then it has just has a black screen so i have to open it up and force a shutdown via the power button

Was this before or after you spilled a drink on it?

It's hard to say because the major spillage I did over half a year ago when I used to just use the laptop like a normal laptop, then in September i bought a monitor and i've been using it with a book arc stand since. I did spill another drink however it only splashed the top lid while it was closed in the stand so it seemed fine

Can't say for sure, software issues like that can stem from anywhere. Some other thread interfered with the dock causing the error.

That is most likely a hardware issue either related to heat (which does seem unlikely since it's sleeping) or possible drink spillage.

If it's just the dock and it was fixed by restarting the dock, it doesn't sound like a hardware issue and perhaps just a software one.
