Caret is scaled improperly while moving shell between monitors with different zoom

[amartya4256]

Exisiting Behaviour: While moving a shell with an editor between monitors with different zoom, sometimes the caret doesn't update its size with the current monitor zoom and still has the zoom of the previous monitor making it look bigger or smaller.

Expected Behaviour: The caret should always scale to the current monitor zoom.

For me it currently happens always and I can even reproduce it in a runtime client. I switched back to an SWT state 5 weeks ago and started a runtime client out of it, which also shows the issue.
