If I try this PR on a setup 100% primary, 175% secondary I get the following issue:

To reproduce:

1. Open the ControlExample (with vm args -Dswt.autoScale=quarter -Dswt.autoScale.updateOnRuntime=true) (on primary)
2. Open Tree Tab
3. Change background color in "Colors and Fonts"
4. Move to secondary monitor

I get the same effect on master, when I change the color, while being on the secondary monitor, but it is happening now on DPI change as well (because the handle is now recreated in that scenario as well)

@akoch-yatta If I understand correctly, you refer to the mismatch between box and it filling, don't you? Should we create a separate ticket for it?

@amartya4256 can you please reduce this one to what's not covered by:

• #3031
• #3024

[akoch-yatta]

@HeikoKlare I removed those and rebased the branch on master
