Hidpi: Zoomed-in character on mouse focus is blurred.
I am using a Hidpi display (4k, scaled at 2x). The zoomed-in character popped up over mouse selection is blurred, including both the huge character itself and the font name that is used to display that character. See the image attached.
All other parts are fine, including the large character on the "Character Detail". They are displayed at the correct resolution.
