Hello,
This display bug is hard to replicate, but I'm running a Windows 10 guest with Ubuntu 18.10 host. After I return the laptop from sleep mode a couple of issues will often occur.
First, the gnome lock screen doesn't activate and I am free to continue using both the guest and host system without my password - this almost always happens when the virtual machine is in full screen mode.
Secondly, Windows itself will produce a whirlwind of display issues including missing borders around the windows, missing buttons in programs, etc. It looks like the graphics driver is not properly redrawing everything. I either have to manually restart Windows Explorer or restart Windows completely. Here is a screenshot of one of the problems (but sometimes it looks worse with tearing and missing icons):
Here's another screenshot that looks worse with the windows settings app open after sleep (without Windows being full screen):
My system specs are:
- Workstation Player 15.0.2 build-10952284
- Ubuntu 18.10 (Gnome 3.30.1, stock settings from the install)
- Kernel 4.18.0-13-generic
- Using X (Wayland doesn't seem to work with VMware)
- Dell Latitude 5591 with i7 8850H and Nvidia GeForce MX 130 graphics
- 16 GB RAM
- 1080p touchscreen display
- Windows 10 is using 1809 and has 2 CPU cores, 4 GB RAM, and 1 GB of graphics with 3D acceleration enabled.
Thanks,
Ian
