Audacity

Audacity seems to have had a long-standing bug on Linux operating systems I have used, and it continues with Kubuntu 25.04. The editing area glitches and doesn’t update unless you resize the window, making it tremendously unsuitable for editing.

I looked it up and found a solution on the Audacity forum.

So, what I do is:

$ GTK_IM_MODULE=audacity
$ flatpak run org.audacityteam.Audacity # since I installed Audacity using Flatpak

This seems to resolve the issue.
