Is this SWT only or the IDE? Which theme are you using?

I not found the use-case of CBanner in IDE 4.14.0.20191212-1200; The case of CTabFolder in IDE 4.14.0.20191212-1200, use CTabFolder.setSimple(true) style.

I used  CBanner and CTabFolder in a RCP program, and use setSimple(false) style, in HiDPI screen ,it looks very rough and not smooth.

Mike, please have a look.

I'm not at all familiar with the cbanner, but if using the CTabFolder set to simple, it appears that CTabFolderRenderer is using SWT.COLOR_WIDGET_NORMAL_SHADOW for the outline. 

I think this is an SWT issue and not a Platform issue.  To add to that, I suspect it's a WONTFIX.
