On buster , if in a gnome xorg session, I * use ctrl-alt-tab to get to the top bar
* hit shift-tab to get to the system menu * arrow down to the bottom * arrow left to settings * hit enter Orca announces the settings frame, but fails to interact with it. Lots of CPU gets consumed and the system generally hangs until I hit alt-f4 to close the settings frame. I'd be interested in any advice on how to debug and isolate what's going on so I can get something concrete enough to file a bug report. --Sam
