Public bug reported: Audacity doesn't work here on either focal or eoan, because the main section of the window (where the waveform should show up and where you click to make selections) doesn't draw at all, as if it's never getting expose events.
I'm using the Openbox window manager, not the Gnome desktop. I'm seeing the same behavior mentioned for the i3 window on arch manager in https://forum.audacityteam.org/viewtopic.php?p=391004#p391004 and I've seen reports of it happening in other WMs as well. I'll attach a screenshot, but really the report in that audacity forum post covers it. So why am I reporting it as an Ubuntu bug instead of upstream audacity? Because according to that report and a few others I've seen, and most of the build documentation for audacity (which mostly recommends using gtk2 rather than gtk3), this is a wx-gtk3 problem: compiling audacity with wx-gtk2 instead of wx-gtk3 fixes the problem. I have not been able to verify this, because although I've been able to build audacity from source against libwxgtk3.0-gtk3 (the problem still occurs), focal doesn't provide a wx-gtk2 option, and I haven't managed to get wxWidgets to build for either gtk2 or gtk3. No one seems to understand what the core problem is that makes audacity fail to draw under wx-gtk3 in some window managers, just that it happens (which makes audacity completely unusable). But if wx-gtk2 was available, audacity built against that might well work for everyone.
