Yes, please, I would be glad to test the patch. (So, the problem was with the "Clear calibration" button, not with the "Software Despeck" option...)

Here are the screenshots (I recreated the "bug" by re-editing the config file and setting the { "clear-calibration" : null} option again). As you can see by the timestamps of the screenshots, it lasts almost two minutes until the warning window appears; program is frozen (not the machine though). HTH, tell me if I can help further

Thank you for your quick reply. Workaround "edit gscan2pdfrc to remove clear-calibration option" worked, no more reload-recursion-limit errors now when I set or unset the "Enhancements / Software Despeck" option. I will ignore the unpaper warnings, results are ok; but those messages could intimidate and turn away some unexperienced users? Keep up the good work! Cheers

Hello all, same issue here: when exporting to png or jpg with "Colouring: coloured", the "black/white" layers appear white; that is, if I choose "Background: white" they cannot be seen... What I expected: "black/white" layer appear white with the option "Background: black", but have to appear black with the option "Background: white" selected! Or am I missing something? (Everithing is fine if you choose "Colouring: black & white"...) Cheers, Dan (librecad 2.1.3, qt 5.11.2 on linux 4.18 and i3wm)
