Applying a linetype makes hard to pick curve

I am experiencing a strange phenomenon in the latest WIP. If I draw a curve in Wireframe mode, the curve has a certain default print width. I have a 4K screen here, so I would say it’s around 3 px using V7 for comparison. If I then then apply a linetype - say dashed - the curve width goes down to 1 pixel, and it becomes very difficult to actually pick the curve via a mouse click - I have to crossing select it.

If I set it back to continuous, it goes back to the standard width and becomes easily pickable again.

I am testing in a bog-standard default version, all display modes are default. Latest WIP.

Hi Mitch, can you send your SystemInfo, I cannot reproduce this on my end.

do you have by any chance display scaling set to something weird like 150% instead of 200%?

I’m running 100% on 1440p and having no issues on my side.

@Gijs I wish one day to have Rhino Systeminfo to show the windows display scaling, this may help us tracking every possible problem.

Yes, and I don’t consider it ‘weird’, it it the recommended display scaling for 4K monitors (27") under Windows 11. I have two 4K monitors connected to this 12Gb RTX 3060.

I updated my video drivers and blocked the RhinoArtFileExplorer plug-in which was seemingly still enabled. SystemInfo updated above. No change in behavior.

I don’t think it is related to scaling. I tried on couple machines with other scaling than 100 (one is set to 125) but I cannot see the phenomenon that the curve thickness changes.

Hi Mitch -
I’m not seeing the thickness change here but don’t have comparable hardware to test with.
I’m seeing the selection issue and will write that up.
