| GIMP not utilizing NVIDIA GPU on Manjaro Linux |

Hello, I'm running GIMP on the following setup:
- OS: Manjaro Linux x86_64
- DE: Plasma 5.27.11
- Host: OMEN by HP Laptop 15-dc1xxx
- Kernel: 5.15.154-1-MANJARO
- CPU: Intel i7-9750H (12) @ 4.500GHz
- GPU: Intel CoffeeLake-H GT2 [UHD Graphics 630]
- GPU: NVIDIA GeForce GTX 1650 Mobile / Max-Q
- Memory: 3296MiB / 15804MiB
I have OpenCL, OpenGL (EGL), OpenGL (GLX), Vulkan, and optimus-manager installed.
I've tested GIMP both in hybrid and NVIDIA modes with LTS 5 and 6 kernels.
When I run:
prime-run gimp
or
DRI_PRIME=1 gimp
GIMP doesn't appear in nvidia-smi, indicating that it's not utilizing the GPU.
I've enabled OpenCL with gimp --show-playground and other settings, but still no luck.
Question:
Is this a problem that can be resolved, or does GIMP only utilize the CPU and not the GPU? The issue is that GIMP has very poor performance when handling layers; it's excessively slow.
Thank you for your assistance with this.

| How to edit existing path? |

I made my first path yesterday.
And exported the pic to a .jpg
All very well.
Opened the xcf today and there is all is, path and all.
I made the brush too wide. The path is too thick.
I want to make it narrower and perhaps move it a bit.
I've clicked paths/edit mode/design, then edit, then move and done no good with any of them. Can't make anything happen.
Then I've found the dockable dialog 'paths' but that hasn't helped.
My cursor remains as a cross above an arc and with a small crossed circle next to it.
How do make this path thinner and move a bit of it ?

I'm a noobie to Gimp, when I 'Export AS..' I have to manually change the file suffix if I want to save as a different file format - is this normal? There is no selection list to choose the file format. I'm using v2.10.36 on a Mac

| How to get TIFF file with 8 bit color depth |

Hello. My goal is to submit a TIFF file with the highest quality possible to Nations Photo Lab for printing. The website for Nations Photo Lab says that the file submitted must have 8 bit color depth. I have read conflicting reports about the color depth of files exported from GIMP. My question is: as a GIMP user, what do I need to do in order to get a TIFF file of a picture with 8 bit color depth? Thank you.

So there is an issue perhaps due to hardware limitations and large images that I cannot click on a pixel of pure black, 0, and use Select By Color with a threshold of 1 to create a selection of all pixels between 0 and 1. I need to select all those pixels in the image with shades of 0.7 and 0.9 for instance. And once selected use the bucket fill to make them all equal to 0
Or at least I need to be able to make all of those pixels between 0 and 1 = 0 by another method. So is there another option open to me? How can I achieve this?
Thanks
