--- Comment #3 from Dmitry Kazakov <[email protected]> --- Git commit a059548b007f99e32533c77e26f0d25650998027 by Dmitry Kazakov. Committed on 28/01/2026 at 12:24. Pushed by dkazakov into branch 'master'. Add Image->Purge Unused Image Data Under some conditions it might happen that some layers and/or projections will contain vast areas of fully transparent data. It can cause a lot of undesirable side-effects, like layer thumbnails recalculating too slowly or image compositing being extremely slow. This patch adds a new user-faced action Image->Purge Unused Image Data, which iterated through all existing layers and removing all fully transparent areas. Just a mere calling to this action can workaround the "slow thumbnail generation" issue as reported in bug 510627. Hence calling to that also switches all the layers back into "precise" thumbnail generation mode. WARNING: calling this action can potentially break Undo/Redo for your image. Please take that into account until the feature is fully tested.
