[Gimp-user] Corruption in layers

[Regor <forums gimpusers com>]

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
