Using the move tool in "move layer with content" mode with Instant Preview on will sometimes appear to move the currently-selected layer, rather than the layer being clicked on. The real image will change correctly, so the preview and real image will get severely out of sync. Switching layers manually fixes the preview. This doesn't always happen, and I'm not sure what exactly triggers it, but it reproduces fairly easily. Create a large image and make several layers with a large brush stroke on each, then try to move them around. Clicking on nearly-transparent areas seems more likely to choose the wrong layer. Reproducible: Sometimes
Hi Eevee, Thanks for your report, and I can reproduce the issue.
I think this got fixed in October when we had the big krita sprint. I cannot reproduce it anymore in any case.
