Un-duping since this should be possible to fix without fixing Bug 356446, and I am investigating doing so.

And upon further investigation and consultation with colleagues, it is impossible to fix without turning on Qt scaling, because you can't selectively turn on or off Qt scaling for only certain UI elements. The only thing we could do is split plasmashell into multiple processes and have one process draw everything that is drawable using Plasma scaling and another process draw everything that needs to be drawn using Qt scaling. Such an endeavor would be an enormous amount of work and add substantial complexity and fragility though, so it's not really feasible.

Re-duping to Bug 356446, and I will re-open it.
