Created attachment 129723 [details] Video of no snapping SUMMARY STEPS TO REPRODUCE 1. Open Grid and Guides Docker 2. Check "Show Grid" 3. Check "Snap to Grid" 4. Draw a line on the canvas 5. Use Move Tool to the line around the grid lines OBSERVED RESULT No snapping happens EXPECTED RESULT Snapping happens SOFTWARE/OS VERSIONS macOS: 10.14.6 Krita: 4.3.0 ADDITIONAL INFORMATION See attachment
Snapping to the grid does work but it's flawed in strange ways. This has alwasy been the situation. So, I'll set this to confirmed. The snap action only happens when you're very close to the grid. I think it would be better if this 'snap distance' was a large (maybe adjustable) percentage of the grid spacing The line tool appears to snap at the start of a line, as observed by the initial guide/construction line but the actual placement of the start of the line is at the initial cursor click position. The end of a line does snap to the grid. The Polyline tool does snap to the grid at the start position and all its later nodes. For the Move tool, it does snap to the grid but it's the initial location of the Move cursor which snaps. If you place the initial location of the cursor at a grid intersection then you'll see snapping. If not, there is snapping but it has nothing to do with image content position.
Re-confirmed for 5.2.9. I'd say this is in relationship to bug 420742 and can be sort of filed under the grid and grid snapping being in need of some TLC.
