Still in eclipse 4.4M2. And a switch to Mac OS 10.9 GM did not solve this.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.

I have tested this with 2020-03 and the paint example on Mac OS 10.15.4.
I can recreate the drawing problems.

If you draw som boxers yo sometimes get only draw 3 instead of the 4 lines.

I found this problem within the mylyn attach screenshot.
When you there annotate by example with an arrow line you do not see this line until you click the next button.

Yes please see the attachment from comment #9 as an actual example.

I paint 3 boxes but you see that for the green box one line is missing!
