Unfortunately the design of Qt style sheets has no concept how to handle backgrounds with rounded corners - beside of padding.</p>
<p>When HackStyledBackground is enabled the plot canvas tries to seperate the background from the background border by reverse engeneering to paint the background before and the border after the plot items. In this order the border gets prefectly antialiased and you can avoid some pixel artifacts in the corners. </p>
