Description Antti Savolainen 2018-07-05 16:16:36 UTC 
Video demonstration: https://youtu.be/MEqBdcLNGto

There's nothing more than what the video shows. I insert an image and move it around and it leaves a trail. The trail disappears if you drag the image below or to the right of the markings or if you click on any other tool

Build & Platform:
    krita 4.2.0-pre-alpha (git c16dbae)
    Xubuntu 17.10
Comment 1 Quiralta 2018-07-05 18:25:31 UTC 
I can't reproduce, although that looks like a redraw problem, more likely to be related to the graphic drivers/card/opengl? but I can be wrong.

Git master here too, on Arch with nvidia system.
Comment 2 joupent 2018-07-06 10:01:22 UTC 
Note: this only happens on a QPainter canvas (i.e. with OpenGL disabled).
Comment 3 Halla Rempt 2018-07-10 13:04:11 UTC 
I am pretty sure this also happens with the decorations for the vector tools, and that we've got a report for it somewhere, but I cannot find it.
Comment 4 Antti Savolainen 2018-07-10 13:31:24 UTC 
Can confirm joupent: Toggling 'Canvas Graphics Acceleration' in the Display settings toggles the trail bug as well.
Comment 5 Dmitry Kazakov 2020-09-09 13:58:18 UTC 
Should be fixed with this patch:
