Weird rasterization artifacts

When I try to rasterize circle with modified border thickness I get weird artifacts

Image[Graphics[{Thickness[.2],Circle[]}]]


Anyone knows any workaround how to get rid of those artifacts?

Note: This happens in Wolfram development platform (Online version of Mathematica). I haven't got a chance to find out how the code behaves in desktop version.

$Version 11.1.0 for Linux x86 (64-bit) (March 7, 2017) • The desktop version is fine, even on Linux (v11.0.1). Please do mention the version of Mathematica ($Version). You might try AbsoluteThickness instead of Thickness and see if it still misbehaves. – Szabolcs Mar 15 '17 at 16:14
• I get the same results with AbsoluteThickness. Looks like a bug in online platform, I will report it. – Adam Sikora Mar 15 '17 at 16:21
• It could be a bug in v11.1 for Linux. But that version is not yet released for the desktop. It is expected in a few days. – Szabolcs Mar 15 '17 at 16:32
• While I'm tempted to say you have accessed the Arrival form of Mathematica, sadly, it isn't so. Reported it. – rcollyer Mar 15 '17 at 16:39
• Just define drawBomb[]:=Image[Graphics[{Thickness[1], Circle[]}]] and we can call it feature: Bomb image – halirutan Mar 16 '17 at 3:29
