Created attachment 104376 [details] Loaded TIFF image 1) Create a 8-bit image 2) Draw something 3) Save into TIFF with LZW compression 4) Close Krita 5) Open the image, you'll see a garbage instead of the image Bug 374958 is related, but a bit different. When you use 16/32 colorspace, Krita saves garbage not depending on the kind of compression.
Okay, this is a regression in master, it works in 3.1.2
Git commit 7e68041f796e4cf23cc3427b4ba6f46d6a098f69 by Dmitry Kazakov. Committed on 21/04/2017 at 11:02. Pushed by dkazakov into branch 'master'. Fix saving of TIFF files Don't use ad-hoc conversion between KisPropertiesConfiguration and KisTIFFOptions, but use a centralized functions instead. Then you can clearly see that '+1' in is forgotten for predictor and faxmode! :) M +8 -55 plugins/impex/tiff/kis_dlg_options_tiff.cpp M +0 -1 plugins/impex/tiff/kis_dlg_options_tiff.h M +57 -1 plugins/impex/tiff/kis_tiff_converter.cc M +12 -9 plugins/impex/tiff/kis_tiff_converter.h M +3 -51 plugins/impex/tiff/kis_tiff_export.cc https://commits.kde.org/krita/7e68041f796e4cf23cc3427b4ba6f46d6a098f69
