[BUG] Incomplete display of hierarchies due to scrolling

[srcds]

Issue: On the right side of the Configuration transformation view, the visualization of hierarchy A can be affected / made incomplete, by using the scrollbars from a hierarchy B. This bug was confirmed for ARX 3.9.0 and ARX 3.9.1 on Win 10.

The following setup can be used to reproduce an extreme example:

1. Open ARX and the example.died from the data folder

2. Click on the "age"attribute and resize the ARX GUI until a vertical and horizontal scrollbar appear on the attributes hierarchy preview.

3. Click the scroll down as well as the scroll right arrow once.
   

4. Click on the “sex” attribute. Parts of the first row and first column are now missing.
   

Further observations:

• The “sex” attribute's hierarchy is displayed correctly again once you scroll back to the upper left corner of the “age” attribute's hierarchy.
• The incomplete view of the hierarchies can not be fixed by re-opening the project.
• The missing/incomplete first row is caused by vertical scrolling; the incomplete first column by horizontal scrolling

I can reproduce it.

On which OS? I could imagine, that this relates to the swt library used. On Mac OS the bug could not be reporduced.

Thanks for the info. This seems to be hard to fix and is only minor. We should put this on our agenda for the next version and the first attempt should be to update nattable to a more recent version.

Just checked on Linux Ubuntu 20.04, and I can NOT reproduce it. Probably it is not an issue in Mac as well.
