Description Sarika Sinha CLA 2019-11-22 11:07:09 EST 
Can reproduce with 4.13 as well as 4.14 M3 build.
Steps to reproduce:
1. Launch Eclipse with any Java version
2. Launch Child Eclipse with Java 13
3. Making a part smaller, reduces the font size but shows the whole content. The other part will have increased font.

Any view or editor? Please provide exact steps.

On Windows 10 it works fine for me for Package Explorer and Outline. Can someone else on Mac confirm this?

I only see it in the editor and only while dragging. After that, the font looks OK again. Correct? Please also test with the Text editor.

Works for me on Windows 10.

Works fine with I20191120-2335 on Windows 10 using steps from comment #0.

Text Editor, Ant Edit behaves the same. It's not only while dragging, looks like it depends on some lemgth less than it remains distorted even after the drag. Even Outline view gets distorted.

Another fact is: It happens only in Java Perspective. Works well in Debug perspective.

I observed this behavior when experimenting with native dark mode, see Bug 540357 Comment 7 (see Bug 540357 Comment 2 for link to cocoa release notes).

I looks like Java 13 is linked on newer macOS, so usage of newer macOS APIs is triggered when launching as nested eclipse.
Comment 11 Lakshmi P Shanmugam CLA 2019-12-09 03:29:21 EST 
I can't reproduce this problem on macOS 10.15.1 with child eclipse launched with Java 13.
Comment 12 Lakshmi P Shanmugam CLA 2019-12-09 05:19:26 EST 
Tried on Sarika's machine, the problem happens with Java 13 but not with Java 12.
But, looks like both Java 12 and Java 13 are linked with 10.12 (checked with otool -l). Also, it's strange that it happens with Java & Plug-in perspective, but not in Debug or Git perspective.
Comment 13 Alexander Kapralov CLA 2019-12-17 13:54:43 EST 
I have same bug with Liberica JDK 11.0.5
Comment 14 Lakshmi P Shanmugam CLA 2020-12-01 07:10:18 EST 
@Sarika, do you still see this with the 4.18 latest builds?
Comment 15 Sarika Sinha CLA 2021-02-10 00:28:08 EST 
Works fine with I20210207-1800 and child Eclipse launched with Java 13.
