The develop module shows a lot of grain when the gpu processor is active

When I enter the develop module, the image starts to appear dim and with lots of noise, but after a few seconds, everything is "normal".
However, since the last update, the image never gets "normal" unless I disable the GPU. This had not happened before (last version).
This may be more or less noticeable, depending on the image, but in all of them, a grain increase occurs when the GPU is active.
I have already confirmed and my drivers are up to date.
I am using a GeForce GTX 960M (notebook) and RAW files are from a Canon 6D Mark II

Well, leave the GPU off then; it doesn't improve things for everyone - it isn't supposed to!

After such useful advice, I feel I have to reciprocate.
Here it goes: "If you buy a car and it does not work, take a bus".
So paying for software in 2017 and expect it to use the capabilities of a graphics card, is iconsidered a luxury?
No, it's not.
In fact, I'm sure that thousands have this problem but they have not stopped yet, because (in my case), you only notice when the ISO is higher.
I know the programming world is extremely complicated due to the infinity of hardware combinations that exists, but it's not at all admissible for a company like Adobe to do nothing to solve the problems of  their customers.

Same thing on a 2017 iMac 27" with AMD Radeon Pro 580 (8Gb) graphics.

Hi, David

I have done several tests and I have noticed that when the photo was made with a very high ISO, the problem is much more noticeable.
When the photos have an ISO of 100, barely notice.
It's obviously a bug, because when I zoom in, the noise disappears (in my case).
It's curious that you have a similar problem with a Mac and an ATi card.

I have this problem with LR 6.12 on an lenovo P50 with nvidia quadro 1000 too.
It is not everytime but sometimes and then the whole session.

If you zoom to 1:1 does the grain disappear?

Thanks for the confirmation. This is a known issue and we have a fix scheduled for the next Lightroom update.
