Task manager window preview not working

Hi,

Recently I’ve been thinking of replacing Windows with a Linux distro on my PC so I installed the latest stable build of Manjaro in a VM to get things setup and work out what kind of packages I want before doing the actual install on my PC.

I ran into the issue of the window previews when hovering over a program in the task manager/taskbar showing just an icon of the program and not the window preview as expected. I’ve tried setting Keep Window Previews to Always in the compositor settings and trying different rendering backends including opengl 2 and 3, but the previews still seem to be broken.

Screenshots below:

Incidentally I was testing out Arch before and the window previews seem to work on there so I’m not sure if there’s a bug or if something is missing on the Manjaro install. Using X11 on both systems.

Arch:

The output to inxi -Fxzis:

Help with this really appreciated, thank you. :slight_smile:

What’s the output of both inxi --admin --verbosity=7 --filter --no-host --width under Arch and Manjaro because it looks like the Arch install had a dGPU passthrough and the Manjaro install didn’t, because that just works on my Manjaro KDE system (Bare metal) out of the box just like in your Arch VM.

:thinking:
