Here's the title clip created. It doesn't appear on either clip or timeline view window.

SUMMARY
When I create a title clip, it comes up empty both in clip view window and timeline view window. The text is not there, therefore it is completely empty and non-functional. I cannot use title clip function as of 25.08.2. This issue was not present in 25.08.1. Tried both appimage and flatpak versions and both have this issue.

STEPS TO REPRODUCE
1. Create a title clip
2. Put title clip in timeline

OBSERVED RESULT
Text in title clip is invisible in either clip view or timeline view window.

EXPECTED RESULT
Text should appear as expected.

Think I've figured out the issue. Size W parameter is set incorrectly for title clips. It is set to 0, 0 by default so the clip titles have no size, therefore invisible. Realized this when I tried the latest daily build. In the daily build, Size W is set to 0, 0 and the resize box in clip viewer shows a tiny box on top left.

In stable build, however, it shows 2560, 1440 as fake values for size W. So the resize box shows as normal but that's a fake value. When you manually resize the title clip, issue is fixed and title clip is visible again. I am guessing there is a bug in the function that sets parameters incorrectly.

Clearing all config files fixed the issue. Title clips are working as they should now.
