displa issue on audacity 2.4.2


I have issue with a bar of audacity in v2.4.2.
I use ubuntu 20.10 with KDE.

In attachement you can see my issue.

I did not have such issue in previous version of audacity with ubuntu 20.04/19.10
As you can see some dropboxes are not fully displayed and selected value is not displayed too.

How can I fix it ?

I doubt that you can “fix” it, but you may be able to “improve” it by dragging the right edge of the toolbar to the right so that the toolbar is wider.
(I believe the problem is the result of minor incompatibilities between different versions of gtk.)

It seems you were right as the issue disappeared once linux librairies have been upgraded
