Malformed audio setting screen

Since Zoom version 6.4.10.2027 and now with Zoom version 6.4.12.2180 on Ubuntu 24.04 my audio settings screen is malformed.

For me in Zoom version 6.4.6.1370 is the last version where the audio setting screen is working correct.

The problem of the audio setting screen is that the the screen is divided in half because the right vertical slider bar is placed in the middle. Because the screen is cut in half, you can not use the audio setting screen normally. The function which are accessible on the left sight are working normally. How can I fix this problem? Or if it can not be fixed by the community, how can this problem forwarded to technical support. I have a free account.
