I have been using Audacity successfully on my xubuntu 20.04 laptop for quite a while, thank you developers.
I have just installed Audacity 2.3.3 on my desktop machine, also running xubuntu 20.04 and it has a very strange display problem. The track display area doesn’t get updated, symptoms as follows:-
1 - If I open an audio file I get the initial display but if I hit play the sound plays but nothing changes in the track display area, no ‘play bar’ moving across the tracks.
2 - If I move from another workspace back to the one where I have Audacity running the track display area in Audacity has a sort of ‘window’ into the previously displayed workspace
3 - When I start Audacity the splash screen isn’t shown, there’s just an outline with nothing in it.
4 - If I resize the Audacity window the track area gets updated but just once.
Other programs all work pretty normally and this isn’t an old or slow system really - I5 processor, 8GB main memory, NVME SSD disk drive, etc.
I also tried running Audacity on my laptop via an ‘ssh -X ’ from my desktop (i.e. program running on laptop, displaying on desktop screen) and that worked OK, so it doesn’t appear to be a specifically screen related problem.
Any ideas anyone what might be wrong?
