No Window title of P2D surface in Activities bar on Ubuntu 20.08

[paulmgartside]

Description

When I run a processing sketch with the default renderer the sketch window (surface) opens, and the name of the sketch appears in the task bar (activity bar) at the top of the screen. (I am running Ubuntu 20.08.)

However, when I run a processing sketch with the P2D renderer the sketch window (surface) opens, but the name of the sketch does not appear in the task bar, instead I see `Unknown' as the title of the window.

Further, when I try to share the sketch window in Zoom - if the renderer is the default one then Zoom sees' the sketch window, and offers it as a choice to share, but if the renderer is P2D then Zoom does not see' the sketch window, and does not give me the option to share. (This inability to share a P2D window via Zoom is the real difficulty I am concerned about.)

Perhaps I should note that in order to run P2D without errors I have `System.setProperty("jogl.disable.openglcore", "true");' in settings(). (This is a known issue.)

I am running Ubuntu 20.08 on dell xps13. Processing version 3.5.4.

Thank you for any assistance - I appreciate it. And my apologies for any impreciseness with my query.
