Android-Bugs: QListWidget , QTableWidget, Editing and Scrollbars

this bugs appear on android , on the desktop version, no problems<:
1) I add an QListWidget, and then on connect->clicked, I choose to edit the currentItem. And the test in that opened editor, is cut on the top and lower part. If I add more elemets, and the screen feels, then the scroolbar appear, but painted completely wrong, it's everything black. You can use that black strip as scrollbar, just it doesn't look like a scrollbar.

2) I add an QTableWidget, and notice, when editing elements (text), again, the text is cut at the lower and upper part. Then I add a column with a QComboBox and I notice that the element is cut again, and you don't see the upper and lower part of the element/text.
What also doenst work, is resizing the columns. In contrast to the qlistwidget, here the scrollbar is painted correctly.
