Inability to preview adjustment brush

[westcopake]

Has anyone solved this problem? Since the latest Raw update, we have lost the ability to preview the adjustment brush, graduated filter and radial filter. I am not talking about previewing all changes made on all other panels - just the ability to preview these individually. We have that ability with the editing panels, but no longer with the above tools. This makes it hard to just see the changes you have made with any of these tools alone.

Yes, lost the ability to use white balance eyedropper, radial and Graduated filters and now the adjustment brushes stopped working.

First, try disabling GPU in the preferences (Preformance). Any better?
