Comment 5 for bug 1860268

Also, some other desktop elements like tooltips, drop down lists or even the selection rubberband box of the screenshot feature are affected. It seems, that the the similarity of this is a comparable small *height*. The rubberband selection for instance is disturbed, if the enclosed height is about less than a few lines and this is totally independent from the width.

For comparison, I create some squares with a bitmap editor: The quirks seems to have "shifted" band sections with a height of 8px. It disappear, if the height reaches about 8*8px. More exact, it aligned to height mod 8 and disappear, if (upper-lower) mod 8 >= 8.
