In HIDPI, IDA is unable to correctly display certain elements, such as tooltip text and icon images.
IDA <= 9.1 is based on Qt 5.15.3 (+ a bunch of patches coming from the KDE community), and despite our efforts & investigations, to this day we don’t have a true solution that works in all cases (usually things can be improved with some fiddling with envvars such as QT_AUTO_SCREEN_SCALE_FACTOR - see High DPI Displays | Qt 5.15)
We’re hoping that the switch to Qt6 (IDA 9.2) will resolve those issues in a proper manner.
(I suggest registering for the beta program if you haven’t already, to give it a shot!)
