20067,Screen resizing with VMSVGA produces artifacts if VM is started from a saved state => Fixed in SVN,mskov,,"Hello, 

if a VM is started from a saved state (e.g., by restoring a live snapshot and resuming), then we observe frame buffer artifacts (colored lines) when screen auto-resizing kicks in (screenshot attached). Usually the artifacts are visible for less than a second and the resizing itself is working fine afterwards. This problem only happens if the VM is resumed from a saved state, on a fresh startup all works fine. And we don't have this problem with VBoxVGA/VBoxSVGA adapter i.e, when vboxvideo is used as a driver. So it looks to be a problem of the vmware driver

This problems is more noticeable if VirtualBox runs on top of Hyper-V, because the VM is slower in such mode and the artifacts during resize become more noticeable. And when running on top of Hyper-V, VMSVGA works much better than VBoxVGA in general (apart from resizing) so going back to VBoxVGA is not realy an option.

We tested this with a fresh Debian 9.13.0 installation with Openbox. Let me know if you need the logs (and which logs you need then). ",defect,closed,other,VirtualBox 6.1.16,fixed,,,Linux,Windows
