My audio is warped when I use the text filter

So, I’m trying to make a video and I want to implement some text into it but my audio sometimes gets warped or sounds strange in the duration I use it. It also lags a bit when I use it too. I even have the latest update of Shotcut and it still happens. I am not using an old computer with outdated hardware too (Although, this not a high end computer like the Acer Predator Helios 300). Maybe other filters makes my audio sound strangely as well. Anyhow, if there’s any way to fix this then please let me know.

This is probably just a preview distortion because the computer is not fast enough. If you export, it should be fine. Did you bother to try that?

No, I haven’t tried that. Anyway, thank you.
