You might try increasing the amount of RAM allowed for graphics; or increasing RAM generally in VirtualBox for that VM. Increasing your swap space within the XFCE VM could potentially help.
On the chance that it is only a Chromium-based browser issue, you might try searching from that perspective.
Example; I found a similar report from 2019 wherein a solution was to disable GPU Rasterization in chrome://flags:
Type chrome://flags into the address bar and then ‘gpu rasterization’ into the resulting search box; and disable GPU Rasterization.
A reboot at this point might be a good choice.
Note that issues with Chromium generally have nothing to do with Manjaro. 
Screenshots (especially of text) are generally discouraged when a brief description is all that’s needed.
Until your forum privileges are increased you can post a link like this: https://forum.manjaro.org/
Notice that this allows others to easily copy/paste the the url if needed, despite it not being a live link.
