Skewed Display on rMBP Mid 2014 Model Iris Pro Graphics

[shaggysivirus]

I have had this Mac since christmas 2014 and love it, it works really good.

 

This has only happened twice but when I have opened the lid to use the mac after it has been asleep the display has come back all kinda skewed, and although the mouse moves nothing is clickable or accessible, almost like a system freeze. 

 

A restart usually fixes it and it's fine afterwards.

 

I usually just close the lid and let the machine sleep instead of powering down, I have only been restarting if I need to (updates etc.)

 

Anyone else experience this? Is it related to the documented memory leaks etc. within Yosemite, or is machine already starting to die?

I often open my rMBP lid to a bunch of garbled random colours, but it's only is like that until the resume process is complete and it's fine after that.

Thanks for the reply. I would expect the resume process to be quicker than that though, this remains like it for well over a minute and this has the 256GB Flash drive.

i mean, I guess its not a huge deal as the machine runs perfectly besides this AND it's only happened twice since I got it. I just really wanted to see if this was happening to anyone else and if it was anything to concern myself with. 

 

It could just be that I put it to sleep and I use Chrome as a browser (memory hog) and I haven't attempted to address any memory leaks or anything within Yosemite (ie. reset the SMC and PRAM)

If your super worried, I would take it into an Apple Store. Just over a check. Never hurts to be too careful.

My original retina only wakes up "messy" when I have a lot of gpu intensive stuff open, especially chrome with 20+ tabs. If I wake it up with nothing or a few apps open like text wrangler, mail and sublime it's fine everytime.

But the original retina was pretty heavy on the GPU in "most space" mode / 1920x1200 mode.

But besides this never had a problem. 13" mid 2014 retina sleeps and wakes up like and champ and I leave so much ###### open. 2 browsers (one of them chrome) with 10+ tabs open. Eclipse, sublime, text wrangler, git client, etc.

So I would, just to be safe take it in, especially if you don't plan on getting apple care.

My experience with Apple products is, if it's defective, most of the time it fails within the first few months. There are a few exceptions but Ive never had those problems and if I did apple usually ends up have a special warranty extension for those issues.

[shaggysivirus]

Thanks. I do run it at the highest resolution.

 

Fortunately I do have apple care. I'll keep an eye on it, as its only happened twice and they have been at least a few weeks apart.

Are you running Yosemite? I'm fairly certain this is a bug with the GPU switching functionality...

 

Ever since I upgraded I have had weird issues with skewed display, garbled colours and regular freezes where as nothing is clickable but the mouse will move.

 

This is a common problem with retina MacBooks and Apple don't seem to be acknowledging it, we have had several updates since Yosemite was released and non of them fix it.

 

Sometimes it happens 5-6 times a day, other times it won't happen at all for weeks.

 

I've narrowed it down to times when the GPU's are switching between each other. If you look at MacRumors you will see it is a widespread problem so I wouldn't worry about you having a defective Mac, we're all suffering the same thing.

On the 2012/2013 ones it's pretty much a known issue.

 

The issue isn't with the hardware itself (it's absolutely fine under 10.9) but with the Yosemite drivers. On my 2012, as a stopgap before it got replaced (for this issue) I was able to use the graphics kexts from 10.10 DP1, which actually helped somewhat.

 

The slow waking from sleep is due to hibernation (or "standby" as apple call it). After an hour (I think) of sleep, it writes the entire contents of ram to disk, and has to write it back upon waking up. With 16GB of RAM, this can take a few seconds (hence the delay).
