The icons in the panel (including the K menu icon) don't scale anymore after upgrading from kde 4.3.5 to 4.4.4. I make my panel rather tall, and the icons used to scale up, but now they're stuck at 32x32. Only one icon, for the desktop folder, still scales; I think that's an svg. I'll try to attach some screenshots. Reproducible: Always Steps to Reproduce: 1. Start kde 2. Look at the panel 3. Weep

Confirmed here, they don't scale equally.
Added upstream bug.
Upstream says it's fixed in kde-4.5
