Drawings on Dynamic Lighting layer are not affecting Dynamic Lighting

Hi all, pretty much as the title says - my wall drawings are blocking the light as they should, but the bars to my cell aren't. Same colour, same layer - granted different shapes but still... Any ideas? First time using the new Dynamic Lighting (used the old one extensively) so I'm guessing it could be something I've done. Thanks in advance. Edit 1 - using Chrome and ''use hardware acceleration if available'' is on. Edit 2 - tried using firefox, exactly the same issue. Switched to legacy dynamic lighting - all works fine. So... seeing as I ran the 'convert all pages to updated dynamic lighting' thinking this would be an improvement, anyone know of a quick way of putting everything back into 'working mode'?

Seem to recall that UDL has that behavior for shapes made with the ellipse tool. Some people are actually exploiting that bug to make "windows" that you can see through but still block movement. Try replacing the circles with short horizontal lines.

Great - thanks for the response David. I've gone back to legacy dynamic lighting now though - reading the forums updated DL just looks too wonky to trust at the moment.

Probably worth noting that LDL also carries the recommendation to only use straight lines on the DL layer.

That said, I've used LDL extensively and have never had an issue with using all the drawing tools to create barriers. Plus of course this exact example works fine using LDL...
