Fix T89405: Viewport Render Preview glitching (AMD)
AMD Drivers didn't report an additional space in the rendered. This made
testing for the HQ workaround fail and the issue appeared back on
certain cards.
This fix will test with surrounding spaces or if the renderer name
endswith the given string. If any of these are the case the hq normals
workaround will be enabled.
