Text Simple bug with GPU efx on

What is your operating system?

What is your Shotcut version (see Help > About Shotcut)?

Can you repeat the problem? If so, what are the steps?
The text simple filter, doesn’t update itself previewing the timeline video.
It’s always the same after the first update.
I have to admit that I’m still using, after 2 years, the sealed version for Win7, which I find more stable. This time I’ve given the latest version a chance.

The final rendering of the video moreover has some visible bugs. Video transactions “white” themselves for a second, and old frames appear for another second, while the correct version of the video is showing…
Lots of strange bugs.

Here is a clip.
Thank you.

PS - the worst bug - the video cannot be opened without GPU OFF, if originally it was created like this. I don’t want to edit anymore the same things, so I will keep the bugs…

(Tomorrow the final video will be available here: https://youtu.be/Pwp7ruS0aUk )

This is probably the same root bug as previously reported about still images with a workaround:

This (text clips on a track above) is fixed for the next version, probably 24.06. (I have not reproduced the glitches you reported.)
