VirtualBox is unusable.

Crashes occurs on:

  • Linux (different kernel version) and Windows 10 guest OS (I have not checked other systems).
  • different VirtualBox versions: 5.2.38; 6.0.18; 6.1.4 (I have not checked other versions)
  • different Linux host kernel versions: 4.14; 4.19; 5.5 (other kernel versions not checked)

Please help to investigate.

#19482 fixed Soft keyboard click-sensitive area offset from drawn button if multimedia keys turned off Rich McAllister
Description

Start a VM in normal GUI window mode (I used an Ubuntu live cd, but I don't think the guest os matters.) Display the soft keyboard with Input>Keyboard>Soft Keyboard.. Open the Soft Keyboard settings and turn off Multimedia keys. Now hover the mouse near the top left corner of a letter key, and note that the key above the key pointed to highlights. For example, hover in the top left corner of A and Q will highlight (US/English keyboard layout.) Click on that spot and the highlighted letter is typed. Moving the pointer around the soft keyboard, it seems that the sensitive areas are still where they were when the multimedia keys were displayed, and didn't move when the multimedia keys were turned off, though the drawn buttons do move.

This behavior observed on a Linux host (Xubuntu 20.04 beta) running VirtualBox t.1.4, and also a Windows 10 host running VirtualBox 6.1.2.
