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 >Hello >reinstalling >installed >normal standard repo issue from which Distro >on specifics to narrow down the cause >are it's a simple fix - Let's hope so Attachments: * https://www.gimpusers.com/system/attachments/1416/original/Alpha_Threshold.pdf -- Regor (via www.gimpusers.com/forums) _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
