Wm_Paint CPU_TIME

Hello,

When updating our product to Eclipse 2019-06, we noticed some performance loss in all our drawing operations, notably the Composite.WM_Paint(long,long) execution.

We would like to know if this performance loss is known?
If that is the case, is this problem solved in future versions?

Do you still see this in 2020-09? to check, get latest I-Build from https://download.eclipse.org/eclipse/downloads/

If yes,could you provide fixes to improve the performance in this area?
