Is anyone else using an M1 MBP with the LG 5k display and experiencing these lines every now and then?

I experience the same with a new LG 5K running off an M1 mini. It’s pretty rare. I restart the machine to be rid of it. I haven’t tried unplugging and re-plugging. Guess we should at least report it, as the monitor’s sold through Apple as a compatible item. It’s been so rare for me, it hasn’t bothered me enough to get that done but I’ll do so now.
 
I have an Intel 13" MBP and have had that a couple times also, so I don't think it is limited to M1 Macs.

Same here. Have you had Bluetooth drop outs with your mouse as well? What is your plan? Are you going to wait and hope for a firmware update?

Yeah also having regular Bluetooth , mainly with the mouse but also keyboard sometimes as well. Annoying but I’m hoping a fix will come soon
 
Yes that has happened with the right side of the display dropping down a few pixels. If you unplug the thunderbolt cable it and plug it back that fixes it. Annoying though.
 
yes...as others have said, resetting the cable fixes the issue.

are those with the 5k able to get 3200 x 1800 resolution? I'm maxing out at 2880 x 1620.
 
Yes. I reported this to Apple via Feedback couple of weeks back. I don't see it much anymore under 11.2 Beta.

BTW, you don't need to replug the cable - you can just put the machine to sleep and wake it back up.
 
Has anyone here had problems with minor freezes in specific programs when plugged into their 5K monitor, but only when plugged into the external monitor? I use PHPStorm and there are a few actions that are a touch laggy unplugged, but sometimes results in application freezes of up to 5 seconds when I'm plugged into the 5K. The puzzling thing is that these are not processing intensive actions. The hard hitting stuff is no problem.
 
Since I installed 11.5.1 on my M1 Mac mini, I have not seen the pixel shift problem.

What are other people's experience?
 
PLEASE let us know if it comes back. If it’s fixed I would seriously consider buying one for my MBP!

I'd been getting it once or twice a week--putting the LG 5K screen to sleep for two seconds cured it. But now that you mention it, I haven't seen the pixel shift since 11.5.1 arrived.

How long do you want to wait? :)

I suggest if no one reports they are still having the problem in the next week, I think you are good to go.
