Googling around I found this: https://bugs.freedesktop.org/show_bug.cgi?id=87478 which puts some blame on Qt's shaders for distance field text rendering.
Happier news is that Qt has options to either use a lower quality distance field rendering approach (fewer ALU instructions) or disabling distance field approach completely. Env vars to play with (I don't have the hardware to test with): QSG_DISTANCEFIELD_ANTIALIASING=subpixel/subpixel-lowq/gray (subpixel the default I believe) QML_DISABLE_DISTANCEFIELD=1 I would also suspect the UbuntuShape is guilty, we probably need a low quality version of it too. ** Bug watch added: freedesktop.org Bugzilla #87478 https://bugs.freedesktop.org/show_bug.cgi?id=87478 -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
