Gradient from border |

Wondering if someone could give me a little help. I used an stl i modeled to create a grayscale heightmap for CNC carving but the outer edges are too steep (see red circle).
I figured I could fix this by applying a gradient around the boundary selection of the image in gIMP to soften the edge between my greyscale image and the black background.
After some google searching I saw there was a tutorial for gradient border select, and the image looks to be similar to the affect I'm trying to achieve, but it was on gimplearn, which seems to no longer exist.
I've included pictures of the greyscale image, what the result is in my carving software, and a picture of the effect i'm trying to achieve.
Any and all help appreciated!
Edit: seems most image hosting service are blocked on my work's network with the exception of tiny pic, which doesn't seem to load into the post correctly, I have included the links below.

Trying to precisely resize |

Hey everyone, I'm new to GIMP and I usually just google my questions and get my answers pretty quickly, however, this issue I haven't found any answers for and its one that affects the functionality of my work process.
I usually resize covers for paperbacks and hardcovers for Amazon and they have precise measurements for what they want as the covers.
Usually on photoshop, I could get the measurement down to the third decimal place without any issues, this is on my PC experience. However, I'm now on a Mac and I'm using GIMP and when I try to do the same for the resize, once I set it and leave the numbers, it rounds up, so 13.025 inches becomes 13.030 inches and 9.917 inches becomes 9.920 inches.
This won't do as Amazon would come back with an error that the size is still unmatched.
How do I ensure that it stays at the exact numbers I selected?
Any assistance would be most appreciated. Enjoying GIMP as an alternative to Photoshop at the moment and want to continue to do so.

Gradient (Color to Transparent) Dithering Effect |

For a school project, I need to make a linear gradient go from a color to transparent. I'm no stranger to using Gimp and I know the steps I need to take in order to achieve such an effect but a strange issue has been occurring. There's this weird dithering effect on the side that is supposed to be transparent.
I already unchecked the dithering option in the gradient tools but the effect still persists. I've looked up tutorials but none really seem to have this issue. I've even reinstalled Gimp but nothings changed. Does anyone have any idea of what's going on or what I'm doing wrong?

coordinates appear to change |

PROBLEM STATEMENT
The coordinates of a fixed point in a drawing change after i use the move tool to move the drawing around so i can see other features and then return to the fixed point. The error is on the order of 300 on the x axis and 50 on the y axis and varies for each test. If I measure and move a short distance and return, I am within user error of about +- 2 units.
CONTEXT
The image in GIMP is a scanned image of an architecture drawing.
ASSUMPTION
1) when an image is loaded into GIMP, the coordinate system of GIMP is aligned with the scanned data of the image. Hence The coordinates of any one
point in the image should always be the same.
2) Using the GIMP Move tool, the tool moves only the viewer, not the drawing and its cooordinate system.
3) If i quit the drawing without making any changes in it, the coordinates of a fixed point within the image should have the exact same coordinates when
the image is opened up once again. By exact i mean as exact as the user can replicate where he is measuring. I find +- 5 units acceptable variation.
My errors are at least 300 units.
Please straighten out my misconceptions so that i can change what i am doing so that i can scan and extract coordinates with reliability and repeatability.
thank you

Deleting area outside selection also removes inside selection |

Hi All,
I wonder if someone could point me in the direction of a setting or let me know what I am doing wrong.
After making a selection I want to clear the background. I invert the selection and press the delete key to clear the selection. The problem I'm having is that it is also fading a little from outside of the (inverted) selection. I.E. fading a little from the part I want to keep.
Here is my process. I foreground select the object. Create a layer mask for the selection. Add a white background layer. Select object layer. Invert selection (because the layer mask has carried over some areas I don't want and were not selected. The press delete.
I'm sure it is just a setting but I can't work out which one.
Many thanks in advance for any help.

GIMP keeps locking up |

Xubuntu 22.04.1
GIMP 2.10.32
As reported here:
https://gitlab.gnome.org/GNOME/gimp/-/issues/9039
GIMP has started freezing on me at completely unpredictable times. Sometimes it occurs after a very long session and sometimes it happens soon after restarting GIMP. Today I worked on a medium sized JPG for about an hour. The last step was to adjust the hue. I pressed H, the Hue menu displayed and then GIMP froze. There is no recovery beyond this point. It appears that this can occur at any time, in the middle of an operation or when selecting a new one. This is happening to me multiple times per week and I have not found any common denominator.
My question is: are others experiencing this as well? If so, please respond here and also please add your comment to the bug report. I don't believe this will get escalated until more people indicate that it is a problem.
Thanks.

Smoother Zoom in/out possible? |

The Zoom moves in very ~dry jerky jumpy~ increments. like 100% to 80% to 60% etc.
Would appreciate a totally smooth zoom in/out. Much better for art work habits also as fine tuning to details occurs constantly.
Thanks
