Bug Description

Summary:
---------------------
It goes into black screen for about 20 seconds when increase Guest OS default resolution to max available resolution 1360 * 768 for ubuntu 22.04 daily build desktop in ESXi. After about 20 seconds later, it restore to previous screen resolution.

Reproduce:
---------------------
1. create VM with default settings(video memory 4MB)and install guest OS with ubuntu 22.04 daily build 27-Feb-2022 images in ESXi

2. we login system after finish installation and rebooting VM

3. Select Virtual Machine -> Settings -> Display, select the max available resolution 1360 * 768
   and click "Apply button".

   The screen get black for about 20 seconds and then restore to previous screen resolution.

Expected Results:
-----------------
For step 3, we expect the max available resolution 1360 * 768 screen resolution works well.
If the default video memory 4MB is not enough to support 1360 * 768 and it needs to restore previous resolution, it seems long to stay black for 20 seconds.
