--- Comment #8 from Yi Yang <ahyangyi at gmail.com> ---
OK, I digged the source code a bit more.

The DPI calculation code at core/utils.cpp line 63-81 returned (93.6, 93.6),
while my actual DPI, as reported by Xorg.log, is (187, 189). Apparently
QScreen::physicalDotsPerInchX() and QScreen::physicalDotsPerInchY() are
returning something not quite physical, when Plasma 5 "scale display" gets
enabled.
