REG: Text looks broken in high-dpi

When running Qt Creator on Windows in the latest Qt 5.8.0 beta package, all the text looks busted. It looks like we are scaling to high-dpi but not disabling hinting on the text, so the text layouts are mangled and everything looks awful.

Look at the brokencreator.png screenshot for a comparison with Qt Creator running on Qt 5.7.0. Look at e.g. the word "enabled" for a clear illustration of the problem.
