Yes, it's definitely possible to get these artifacts. It doesn't always happen, and I've seen it with other shapes as well. Artefacts are always present if a shape is moved slowly towards the top left of the canvas. An area around the shape is cleared upon mouse release, but a trail remains if the shape has been moved a significant distance. Seems to be a repainting problem related to the bottom lines of the lower-most handles, and the right lines of the right-most handles. Interestingly, when a shape is moved to the right or downwards those handle edge lines are not always painted. This doesn't seem to happen in Karbon. I've tried messing around with the HANDLE_SIZE macro setting in calligra/plugins/defaultTools/defaulttool/DefaultTool.cpp in an attempt to extend the bounding box during shape move, but that was no help. Usually in updating problems there is a problems with the update rect. So you could start by checking the rect that is updated in the canvas and see if that's at the right place. It also helps sometimes to simply draw the update rect and see if it stays around the shape. Git commit 8a054d066da2bba009a47ff24a8d2dbd86b77c30 by Sven Langkamp. Committed on 03/08/2012 at 01:31.

Created attachment 61560 [details] .Kra File demonstrating text shape artefacts Version: svn trunk (using KDE 4.6.4) OS: Linux When moving a text shape, the handles (the yellow squares used for rescaling) seem to leave artefacts onscreen. Other vector shapes such as the freehand line and calligraphy line don't seem to do this. Reproducible: Always Steps to Reproduce: 1. Open the attached .kra 2. Select the vector layer up the top 3. Select the vector select tool 4. Move the text at the top of the image (especially left and right) Actual Results: Artefacts are left on screen. Expected Results: No artefacts are left on screen.
