[GitHub] [netbeans] rickqinj opened a new issue #3820: The code completion popup overlay cannot display items correctly when user scroll up/down the list.
rickqinj opened a new issue #3820:
URL: https://github.com/apache/netbeans/issues/3820
### Apache NetBeans version
Apache NetBeans 13
### What happened
The code completion popup window may not function right when the window shows up near the bottom edge of the Netbeans IDE's window.
### How to reproduce
This issue is really weird. We can reproduce it ONLY in a particular situation.
1. Coding in Java.
2. Make a statement close to the bottom edge of the Netbeans IDE's window. For example, the statement may look like the following:
```Java
String str = new String();
str.
```
3. Move your caret to the line `str.` and behind the dot.

4. Press `ctrl+\` to call out the code completion popup window.

5. Scroll back and forth the "Option list" by Arrow_DOWN or mouse scrolling wheel or dragging the scroll bar of the Option list.
Then, you will see the Option list could be stuck and don't get refreshed anymore.
Note: the issue only occurs when the first entry in the Option list has a JavaDoc. Everything goes fine If the first entry coming to the Option list doesn't have a JavaDoc(I mean, no need to popup the JavaDoc window).
### Did this work correctly in an earlier version?
Apache NetBeans 12.6
### Operating System
Win10 pro 64bit
### JDK
Oracle JDK 11.0.8
### Apache NetBeans packaging
Apache NetBeans provided installer
### Anything else
_No response_
### Are you willing to submit a pull request?
No
### Code of Conduct
Yes

I think NB11 hasn't had the new LAF - `FlatLaf light` yet at that time. Have you tried it with other LAFs on NB11?

I'm not sure its related with the LAF, but I think I remember this happening in version 11. For me I was never able to reproduce it, it just happened randomly, so I'm not 100% sure

For me, this issue only happens when the code completion list needs to be re-positioned and the first item that appears in the list has a JavaDoc need to display. So, the conditions to reproduce are:
- Code completion list position needs to be adjusted accordingly to the edge of the viewport.
- And, the first item that appears in the Code completion list must have a JavaDoc to display.
- And, Netbeans goes with the LAF FlatLaf light.

Hi, I tried it again with the LAF Windows and found the problem's gone. It seems like the issue was caused by the new default LAF - FlatLaf light.

Were you using the same look and feel when this worked on 12.6? Can you try with an up-to-date JDK? There seem to have been some text related bug fixes since 11.0.8 that might be a cause.
