Vivaldi browser freezes (VMSVGA + 3D acceleration)

[Gwen]

Vivaldi browser uses Hardware Acclereation if on a system.
With Virtualbox 6.0.14 and 6.1.2 the browser starts and freezes completely. Killing it with xkill results in a crash of VirtualBox.

The only way to start Vivaldi is to disable 3D in VMSVGA or to start vivaldi with

Code: Select all

vivaldi --disable-gpu

.
But this will disable all video decoding in Vivaldi and slow down the complete guest.
