Not using custom xml but 1.08 , this issue is on 1.08   default status .

Ok. What happens when you restore to default settings? If it’s not fixed, please tell me your display resolution.

It's 3840x2160, i think if we resize left panel width slightly then it might not over shadow widget pictures. May be other don't have this issue.

OK I see the issue. 

You're using the widget zoom Achilles created. There's a diffuse mask associated with the left panel which is designed to mask the widget as it crosses into the left panel.  The zoom is pushing the focussed widget slightly into the mask area so a tiny part is being masked. 

I could reduce the mask width slightly to compensate the zoom but the problem is, I'm actually looking to slightly increase the mask width once we bring back fixed frame! Currently, you can see the mask's edge as the widget crosses into the left panel because the frame moves. But once we bring back the fixed frame and increase the mask width, the frame will completely hide this edge since the frame won't move.

I'm sure I can work something out though but it's best to just disable the widget zoom for now or live with it for the time being.
