Description Niraj Modi CLA 2020-05-21 06:13:05 EDT 
Possible regression of Bug 538740 - Add square tab implementation to CTagRendering

Steps to reproduce:
1. Open at-least 3 .java files(also happens with .html files) and focus on first tab.
2. Now mouse hover over the second Tab and slowly move from Left to Right, make sure to move over the second Square Tab's Close button.
3. On entering the third tab header area, the square tab header goes invisible at times partially/fully.
4. Same behavior is seen on all Tab that are present on the Right of third tab.

Problem not seen with Eclipse IBuild I20200506-1800 which has rounded Tabs.

I was not able to reproduce this on Mac. 
If you change the preference to use round tabs in General > Appearance > use Round tabs and restart, do you still see the problem?

This has already been reported and fixed, the Gerrit is still under review.

Round Tabs works as before, so it's a workaround until bug 563345 is fixed.
