Yes, that's to be expected because both of those methods use the viewport realtime display
mechanism. They are meant to just capture the display and are not really intended for
making final presentation graphics.

For better quality presentation images, the PDF or AI exports will work much better, those are
the functions that are more oriented towards making a high quality graphic result and not
only primarily focused on speed like the viewport display is. Or also the other main way to get
high quality renders is to export to a rendering program.

I don't know yet what will be done in this area for V4. I have a few ideas on how to improve
that particular display artifact but it has to be done quite carefully in order to not degrade
the performance of the display engine. So any changes have to be tested quite a bit to make
sure it doesn't come at too high of a performance cost. That type of stuff involves quite
a bit of work and it's difficult for me to predict when such things will be completed. It's very
important for the display to be quick so that it can be interactive, the display engine is just
overall much more focused on speed and not on trying to make a presentation type graphic.

Any future improvements in this area will probably involve calculations done by the CPU
before stuff is sent to the graphics card, and so probably won't be dependent on any
specific video card.
