I recently upgraded to Lubuntu 19.10, and I also changed PC (migrating my installation), so I’m not sure when this happened or what caused it.
When I open Audacity the part of the window where the track is does not render (along with some smaller other parts here and there). If I alt-tab from another application, the track part will keep the screen unchanged while the rest of Audacity pops outside of it. When I record, it temporarily refreshes showing the tracks, but does not update as the recording goes on. The timer bar at the top moves correctly, but nothing else changes. If I reply my recording the audio plays correctly, but again the “visual” part is not working at all.
Audacity is installed from apt, version 2.3.2. In build information it says WxWidgets 3.0.4. I’m not sure if there’s any additional info I can provide. I have tried purging and reinstalling, but nothing changes.
