Font issues with PDF display

When using Beta 32 and displaying PDFs in the editor, the font displays very weirdly. The problem only occurs when High DPI mode is enabled. I’ve attached a screenshot showing the problem–as you can see, the titlebar above the PDF displays fine, but the text of the PDF itself is hard to read.

Edited to add: additionally, the problem seems to be tied to multiple monitors. The difficult text appears on my lower-resolution monitor (1920x1080), but appears fine on my main display (2736x1824).
