if it&apos;s applicable to WebKit.

The problem seems to be the creation of a transparency layer while
painting the background. The solution is to prevent any form of isolation
caused by blending when painting the root element.</thetext>

&gt; The problem seems to be the creation of a transparency layer while
&gt; painting the background. The solution is to prevent any form of isolation
&gt; caused by blending when painting the root element.

This issue is related to mix-blend-mode for software, which isn&apos;t currently implemented in WebKit. Since it&apos;s not applicable to WebKit,  we should probably close this</thetext>
