I can't reproduce this here on Windows. Can you provide screenshots of what it looks like with and without Thick lines for you?

Here are 3 screenshot, one with thin lines and cycles rendering : no problem :
and two with thick lines and cycle with cpu and gpu rendering, both with the same problem : the viewport rendering looks pixelated

Thanks, yes, it looks the same here. 400% zoom clearly shows the difference:

Thin:


Thick:

@Alexandre Labedade (Alesk) Is this still an issue with latest build? If yes, please provide Blender version you tested with.

Yes, I still see this problem with blender 2.81a, freshly downloaded from the main website.

So this will be likely platform / GPU specific. You can try updating your driver in case there is an update.

This is my current driver setup :

And I don't have any other upgrade available for now.

This is intended behavior to save rendering time on high-resolution monitors. This can be disabled in the Performance settings by setting Viewport Resolution to 1x https://docs.blender.org/manual/en/latest/render/cycles/render_settings/performance.html#viewport
