Contour tool and groups

[ashf]

Contour tool does not work with groups properly.

- dragging on the group won't be reflected on the number on context toolbar.

- changing the number(slider) on the context toolbar does not work(can not slide the slider)

In my first attached video I can see some of what you have reported.
In the first part, the Radius value doesn’t seem to change in the Context Toolbar but I’m not sure what value it’s supposed to be shown with more then one shape being ‘worked on’ at the same time.
In the second part, the Radius value and slider exhibit very strange behaviour, just watch the slider and value quickly jump between values.
Note: For some reason, near the end, the pointer changes to the Fill Tool pointer when the Contour Tool is still selected.

In my second attached video I have a group consisting of a Rectangle, a closed Curve layer, an open Curve layer, an Image layer, an Artistic Text layer and a Frame Text layer. (An artificially-random group but something which can be possible.)
When I try to apply the Contour Tool to this group I get some unexpected results.
Note: CPU usage went to near 100% on my fairly basic laptop with 4 physical cores so I had to shut Designer down to stop the fan from ‘busting out’. A previous test (not recorded) had even worse results with the application switching between non-responsive, and responsive but not displaying anything on the canvas. Neither situation is ideal.

My guess is that the Contour Tool has not been fully tested on either groups and/or different types of layers.
I don’t even know if using the Contour Tool has fully-defined expectations on some types of layers – I don’t know what should happen if, for instance, I use it on an Image layer. (Try it and see if you get what you would expect.)

More work on this tool is needed I think.

Apologies for the delayed response here and many thanks for your report @ashf & the further information provided by @GarryP - this is certainly helpful!

I've been able to replicate this here and I'm getting it logged with our developers currently

I can confirm this re-draw issue is already logged with our developers & I suspect this bug is also causing the pinned CPU usage as the app struggles to keep up whilst incorrectly calculating the contour & constantly trying to redraw the object incorrectly.

I'll be sure to bump this log with our developers, and include the further information supplied here, I hope this helps!
