Hi, I'm experiencing the same bug, with Qt 5.7, Plasma 5.7, Frameworks 5.23.
I confirm the problem is not specific to PDFs, but happens with all
document/image rendering in okular. The content appears as though it is
rendered in a buffer sized according to the number of *logical pixels* in the
viewport - which is less than *physical pixels* in the case of hidpi displays
with QT_AUTO_SCREEN_SCALE_FACTOR=1. When this buffers gets displayed, it's
scaled with nearest interpolation, producing ugly large square pixels.
