qtwebengine + webgl on windows, black geometry?
On some windows hardware, using a qwebengineview showing a page with webgl, objects appear very dark or black. Though it may be a texturing issue, nearly all of the examples on webglsamples.org and threejs.org seem fine except lighting-based ones.
the main geometry is completely black when viewing via qtwebengine on our surface pro 3, but on the same computer looks fine via chrome browser. And the same qtwebengine app works fine on a laptop with nvidia graphics.
Any ideas on what's going on here?
