Window content disappears on Debian Buster when maximizing or switching virtual desktop

[jeduardo]

Description

When running Brave on Debian Buster, the Brave window contents disappear when one switches to a different virtual desktop and back to the main desktop (on i3/X11) or when the browser window is maximized (Gnome/X11).

The window contents come back if you open a new window, which forces a resize (i3/X11) or if you restore the window to its previous size (Gnome/X11).

Steps to Reproduce

1. Open Brave
2. Move to a second desktop/maximize the window
3. See empty window inside the window manager borders

Actual result:

Browser window before alternating desktop

Browser window when coming back to original desktop

Expected result:

Expected result is that the window contents don't disappear when switching desktops (or maximizing it, when on Gnome).

Reproduces how often:

Consistent since around 1 month.
