After upgrading to 2.4.2 on Ubuntu 21.04, I can’t see the vertical line indicating the current position when playing an audio file.
So, I can’t ‘follow’ the position in the played file, that is pretty annoying
Audacity does not yet fully support Wayland. This is already logged on the Audacity issue tracker, but it probably requires Audacity to be built with WxWidgets 3.1 (which is already stated to be the required version in Audacity’s build instructions), but package maintainers have frequently built Audacity with the wrong version of WxWidgets.
