      Description

      The GPU blacklist contains some GPUs (Intel Q965/Q963) that disable both desktopgl, and angle.

      Currently the fallback seems to be opengl32sw.dll which is

      • incredibly big (15 MB)
      • incredibly slow

      and thus not very attractive to be shipped as part of a product.

      Is there any reason why the fallback is not the software renderer, which works quite well for QtQuick UIs?

      I understand the need for a full OpenGL software rasterizer when using QGraphicEffects but most UIs should work just fine without.

      Suggestion: Add a QSGRendererInterface flag like "fallbackToSoftwareRasterizer"
