graphical glitch in zoomable light table mode
There is a small glitch in zoomable light table mode that makes the whole package of thumbnails shortly up-left and back again under certain conditions.
Here is how to reproduce:
1) go into a filmroll with quite some images; switch to zoomable light table mode
2) zoom out so that the package of thumbs is halfways in the middle not touching the upper and left border
3) select a few images and press "export"
4) after each image that got exported successfully the package of thumbs shortly jumps up-left touching the upper and left border of center view; then jumps back
to the original position again
Not critical but at least a bit annoying when you watch darktable while exporting images.
