I also have this problem. It's quite frustrating when working with a large amount of strokes. One thing you can do is switching to outline view mode (maybe create a shortcut for this?). Clicking the curve this way will select the right one. It's a workaround, but it might help until the problem is fixed. 

Hi,
I know the mesh fill tool is still on the roadmap and I have some suggestions for it. I understand it will be like in DrawPlus and the mesh fill will be a rectangle placed over the original object, which can then be reshaped and edited. 
In the attached images you can see how working with vertices works in Blender and I actually think it would be very handy to use these features in the mesh fill tool. 
See the description in the pictures. 
Also I think it could be a great feature to actually use the cursor as a brush, selecting a colour with which to directly change the selected/painted vertex's colour. This could even be extended with adding pressure sensitivity to change brush size/colour opacity? 
I realize these might not be easily implemented, but I think it would greatly improve the possibilities and elevate Affinity Designer above other illustration apps. 
Regards,
Zsolt
