MacOS 10.12.4 Graphic Glitches

I have the same issue problem - on internal Macbook display and on external display as well. It happens radomly across all apps, especially in case fast movements like video, scrolling, switching tabs in Safari. When I restart Macbook, the issue disappear for some time, but after some time it appears again. When Macbook is connected to external display and the lid is closed, the problem appears in short time after restart. When I open the lid, flickering disappears, wierd.

Example video (most visible around time 0:07s)

I attach screenshots where issues are highligted.

I tried reset SMC, NVRAM. I tried to close all potential apps. I tried Diagnostic mode. I tried to create new user to prevent it's issue of my account settings. Nothing helps. Issue is still here.

I notice that it could be caused by the last update of macOS 10.12.4.

My machine: MacBook Pro (Retina, 13-inch, Early 2015), 3,1 GHz i7, 16GB, Intel Iris 6100

macOS Sierra, 10.12.4.

Thanks for any help and advice if it's SW or HW issue. Dou think that clean install of system can help?

I have had some odd graphic glitches, I installed 10.12.4 a week or two ago and all appeared ok until yesterday...had to restart a few times. Today I reset NVRAM but haven't had any problems yet, may load up youtube etc to test

Same issue here, the gmail progress bar glitch its exactly as I see in my MBP 13" early 2015 (OSX 10.12.4). The issue appers more often if I use both internal and external display.

This is my 2nd MBP, the first one had the staingate and this one has this:

Similar issues here after updating to 10.12.4 on MacBook Air (13-inch, Early 2015). Have an external monitor connected typically (as an extra screen), but seems to happen on the built in display, not the external monitor in my case. Mostly happening when there is some sort of cursor movement, scrolling, typing, or video playing. Here's a still example of the white boxes I'm seeing briefly on a video that's not currently playing, just on cursor movement.

Here are some lovely artifacts from last night while trying to watch a live video stream. Absolutely unwatchable like this. I sincerely hope Apple is aware and working on this problem. It's heinous.

Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.

Send Apple feedback. They won't answer, but at least will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner.

Hello!

I have exactly this problem with my MBA 11 (2015) after installing MacOS 10.12.4. Apple Support told me they didn't aware about this issue and gave me a workaround that worked for me.

Try to reset NVRAM following this guide:

How to reset NVRAM on your Mac - Apple Support

NOTE: When I change the screen resolution the problem reappears, but I can reset NVRAM again.

Good luck!!

Hi, I'm the one from the video you mentioned in your original post. I also still have the issue, also saw it popping up in Spotify now. Doesn't alway occur though and haven't figured out when it does and when not. Keep us posted on any further info you might find. Thanks!

I'm having the exact same issue as you've listed above. Same model Mac as well. I'm assuming (hoping) that it's related to 10.12.4, and not a hardware issue. Thanks for posting this. Hopefully Apple sees it.

I sent too.

I recognized that it happens especially when my Macbook is connected to external monitor. When the lid is closed, glitches appear. When the lid is opened, glitches disappears. When I disconnect Macbook from external monitor, sometimes glitches appear also on internal Macbook's display. When I restart Macbook, everything is ok. So, if I don't want to see glitches, I have to leave Macbook's lid opened when it's connected to external monitor.

It could be some SW issue of switching GPU between external/internal monitor or something similar.

Hi guys,

I also have the exact same problem on my MB Pro 13" 2015 model with a external monitor connected thru HDMI.

Tried everything "as far as I know ofc" even did a clean install which didn't solve the problem.

One strange thing I did notice "wandering if any of you guys did too"

Usually when booting up my system, I'll wait with closing the lid of my MB till everything is loaded and the external monitor is activated but this morning for some reason...changed up my routine and turned on my monitor first, then powered on my MB, typed my password and immediately closed the lid of my MB even before I saw the loading / progress bar on the internal display. And to my surprise I don't see any glitches anymore what so ever. I tested / repeated this way of booting up my system for at least 10 times and no glitches to be found.

Has anyone tried this as well ?

Hello,
