Audacity 3 Help Forum GNU/Linux
10

The cause of the problem is known. The unknown part is why it causes display problems on some machines and not others.

Another symptom of the same root cause in Audacity 2.4.1 is (and this affects users that don’t have the display problem):

  1. Create an audio track
  2. “View menu > Track Size > Fit to Height”
  3. Crash.

The cause of the problem is that Audacity has been built with GTK3 and wxWidgets 3.0. Up to and including Audacity 2.4.1 should be built with GTK2.
Audacity 2.3.3 doesn’t play well the wx3.0/GTK3 combo. It’s not until 2.4.2 do we get somewhat decent GTK3 support using wx3.1.3.

The Audacity developers are currently looking at ways to prevent Audacity being built with incompatible versions of wxGTK.
