New bug about text

Hi

There is new bug about Fxsound 1.2.5.0.

When I use Fxsound and ues language like Chinese or Japanese from Dark Theme to Light Theme, my texts are disappearing, just have some numbers and English words.

Here is a video can replay what happened with it.

My PC:

Version Windows 11 Pro 25H2 26200.7309
Windows Feature Experience Pack 1000.26100.275.0
