When you switch the language to Traditional Chinese or Japanese, the text throughout the Viewer UI experiences missing characters, garbled text, and font errors. This issue affects not only full-width characters like Chinese and Japanese but also English and various symbols.

Initially, I thought it was due to missing fonts. Later, I discovered that if you drag an open floating window, the text in the current window will return to normal, but the next window page will still have the same error, requiring another drag to restore it. The dragged floating window will not show errors until the next time Viewer is opened.

This issue only appears in version 7.1.11.12363455226. Previous versions did not have this issue.

This issue was initially discovered in the latest test version of Firestorm. Later, I wanted to test it on the official viewer and found that the official viewer also had this issue.

I uploaded a video to help you make a judgment.The first one is an error video appearing on the official viewer, and the second one is an error on Firestorm.
