I have two QT applications — VirtualBox Manager and QT pass. These applications display in very low resolution on one of my machines. The VBox Manager fills the screen so that the dialog controls are buried under the desktop's bottom panel.
Is there a QT tweak I can apply?
This is an issue on only one of my 19.04 machines. It is the only machine I have that uses NVIDIA however switching to the Nouveau driver doesn't fix the problem.
