When using line elements I notice that sometimes the lines are renedered blurry in the browser for files created in axure 9. It appears to happen only when the thickness of the lines is odd. I now fall back on using box elements.
Hmm, I’ve been able to reproduce this behavior when previewing lines with an odd valued line thickness as well. This behavior looks to be unexpected, so I’ll be filing a bug report regarding this with our respective teams shortly.
