Description
After recent upgrade to QT 5.13.1 (probably on or around 15/09/2019) on SuSE Tumbleweed VirtualBox started behaving incorrectly when used on two monitors setup with enabled OS level UI scaling (1.6). Issue happens only on one of the monitors. I am using X11 Plasma with KDE.
When VirtualBox is launched the main window is displayed properly, however when it is resized to full screen (or majority of the screen) severe rendering issues start to show up. The top level menu (File/Machine/Help) disappears, the VM list disappears etc (please refer to the screenshot).
When a VM is started and is displayed in full screen only part of the screen of the guest is visible (see screenshot).
When VBox windows are moved to the other display and are maximized everything is OK again.
Out of curiosity I tested the latest VBox beta version (VirtualBox-6.0-6.1.0_BETA1_133315_openSUSE150) and the issue is there too.

This problem exist in 5.12.5 too. I have two Fedora 31 machines, the UI goes fine in the single monitor machine, and in the multiple monitor it renders extremely broken, both are KDE version of Fedora.
My multi-monitor setup is a bit uncommon, the left ultra-wide monitor 2560x1080 is working as 3840x1620, de right one is a wide 4k monitor. I suspect some bad geometry is happening in multi-monitor setups.

There is a workaround for this issue, just set
export QT_SCREEN_SCALE_FACTORS="1;1"
in your shell before starting VirtualBox.
VBox log
