Dynamically adapt SWT on 'SWT.ZoomChanged' event on single monitor. #127
Description
This bug is to adapt SWT/Eclipse dynamic to changing OS zoom values:
It will require adapting all the SWT widgets to work on the new zoom value.
Note: This is a big ticket item and it will require lot of changes in SWT, here the branch where i could partially achieve this:
https://git.eclipse.org/c/platform/eclipse.platform.swt.git/?h=nmodi%2FDynamicDPI_4909
Since this was partially working then and hence we opted to restart Eclipse on 'SWT.ZoomChanged' event:

This issue has been resolved with the "monitor-specific UI scaling" feature and the according improvements done for it. With that feature, shells adapt their zoom to the current monitor:
Remaining issues with that feature are tracked in this umbrella:
