Corruption in layers

Deleting large amounts of background and cloning the remaining image to create new image.effects. All layers have alpha layers

After a large amount of work, corruption on the layer appears in the form of white pixels appearing in a local area next to the cloning work being done.

The corrupted rogue pixels cannot be deleted, they move randomly when a eraser tool is used on them, they also show through the background image as well

Was using 2.10.8 and the rouge pixels were white. Reinstalled to 2.10.18 the same happened but the rouge pixels are now black

Your help please

Hello

The point about the pixels changing from white to black is bit odd after

reinstalling

BUT did you erase/refresh/renew your config files they stay when you uninstalling gimp even when a new/fresh version is

installed

could be worth checking

Also what distro are you on Linux or Windows version

The Gimp you got from Where site or distro repo is it snap or flatpack or

normal standard repo issue from which Distro

Maybe could be a corrupted file/download if gotten from a non repo site

For anyone to figure this tricky tricky they really could use a lot more info

on specifics to narrow down the cause

I'm Very interested about this one I have not heard of this before all the best and I hope the extra info will help to work this out - Chances

are it's a simple fix - Let's hope so

Corruption in layers

Thanks for your reply and interest

When we reinstalled, we cleaned out all profile settings we could find The down load was from the Gimp site Windows 10
Further checking showed that
The corruption occurred on layers that were duplicated The corruption showed on one user computer - 2.10.18 where the editing was being done, but a copy of the image file containing duplicated layers did not show on another computer which uses an earlier version, 2.10.8

We determined that the problem was connected in some way to the Alpha channel

Our first fix was to add a background layer, and adjusted the opacity to only 1% Refer image 1,2,3
While this fix worked it was not a practical solution

We then looked further at the transparency layer options; Threshold Alpha. The Threshold Alpha default setting was 0.5. This default valve appeared OK; but if you open the preview screen, it shows the corruption. Refer images 4,5,6.7,8

We moved the slider to "1" then "0" then back to 0.5 and, and this value is accepted. The problem was solved. It is as if the default value does not register

This would appear to be an application bug

I hope this is of help to you and I appreciated your offer of help

Corruption in layers

I would say Images editing can be done if we know the steps of the working of layers in the editing tools. There is always some of the reviews of the application which provide the https://edubirdie.org/edubirdie-review-the-most-honest-and-reliable/ site reliable use of the Images editing review options which provides the best option to edit the Images.
