Complete UI looks unstable, all dashboard control elements disappear for a short moment and reappear under particular conditions.

The shown effect (watch LibO Navigator!) in this movie
<https://www.youtube.com/watch?v=zp0JV3_Gx9M&feature=youtu.be> has been taken from Version: 184.108.40.206 Build-ID: 22b09f6418e8c2d508a9eaf86b2399209b0990f4 CPU-Threads: 4; Betriebssystem:Windows 6.1; UI-Render: Standard; Gebietsschema: de-DE (de_DE); Calc: group.
The problem does not only affect Navigator, more or less all other UI-Elements like Menu Bar and others show the same problems.
Currently I can't tell whether there is a common root for these problems.
