Looking at the i915 bug report, it seems like the distance field text rendering shader in Qt has too much instructions (in its HQ version) and exceeds the number of texture indirections, would be interesting to check if the distance field UbuntuShape shader has the same issue.
It would also be interesting to know how much instructions take the alternative (enabled on OpenGL ES 2 when OES_standard_derivatives is not supported) mipmapped UbuntuShape fragment shader (UC_SHAPE_MIPMAPS=1 must be set in the env to force its use). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580792 Title: Unity8 on Intel Atoms performs poorly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1580792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
