On computer with two screens with different DPI (one with 100%, other with 200%), checkboxes look fine on screen with 100%, but too small when app moves to the screen with 200%.

When having only one screen attached (any of those two), the app looks fine in both cases.

When starting the app when only screen with 200% attached, then connecting screen with 100% and moving the app there, checkboxes are too big.

Same relates to QRadioButtons, and dropdown button for QComboBox.

To demonstrate, I used "tabdialog" example shipped with Qt (Tab Dialog Example), no modifications done. Please check the screenshots atached.
