Created attachment 172054 [details] Backtrace SUMMARY When trying to downscale an image while having the grid enabled at 1px spacing, Krita crashes STEPS TO REPRODUCE 1. Create a new Image (Size doesn't matter) 2. Set the X and Y spacing of the grid to 1px 3. Show the grid 4. Scale the image down to a lower size OBSERVED RESULT Krita crashes EXPECTED RESULT Image scales down to the new size SOFTWARE/OS VERSIONS Linux: 6.10.1-arch1-1 KDE Plasma Version: 6.1.3 KDE Frameworks Version: 6.4.0 Qt Version: 6.7.2 BACKTRACE: Downloading source file /usr/src/debug/gcc/gcc/libstdc++-v3/libsupc++/eh_throw.cc [### ] Breakpoint 2 at 0x7ffff54ae260: file /usr/src/debug/gcc/gcc/libstdc++-v3/libsupc++/eh_throw.cc, line 80.

Git commit 6324ca44615fa33957c9d96fdfb16b58d4fe6674 by Dmitry Kazakov, on behalf of Freya Lupen. Committed on 31/07/2024 at 06:33. Pushed by dkazakov into branch 'master'. Fix scaling down image with 1px grid spacing Scaling the image scales the grid along with it. If the scale was less than 50%, 1px grid spacing would be rounded down to 0, causing modulo by zero, or triggering an infinite loop warning in KisGridDecoration::drawDecoration (since effectiveSize == 0). So make sure the minimum spacing after transform is 1px. M +3 -0 libs/ui/canvas/kis_grid_config.cpp https://invent.kde.org/graphics/krita/-/commit/6324ca44615fa33957c9d96fdfb16b58d4fe6674
