RFR: 8225777: java/awt/Mixing/MixingOnDialog.java fails on Ubuntu

[Alexander Zvegintsev]

The test was failing due to it tried to place windows too close to left top corner, so they got shifted from the dock and top panel on Gnome.

Shifting all test windows fixes the issue.


Testing is green on all platforms.
