When using eclipse oxygen core for studio following UI Issues are seen. Refer to attached screenshot as well.
Point 1 & 2 below occur only on windows. Point 3 & 4 can be seen on both windows and Mac. The same code base and screen resolution does not show these UI issues when ran with Eclipse Luna.
1. The Run and Device drop down are shown truncated
2. The logged in User, feedback button and change organization button at the bottom right are not shown
3. When no tab is open then a small black line is shown in the editor area near the left and right edge
4. Extra white border of each view. It gives a feeling of extra lines in the gap between views.
