No video scrolling in QuickTime Player, while playing, after upgrading to MacOS Ventura 13.1

Hello Denisius,

Thank you for reaching out to Apple Support Communities.

If you press on the forward or reverse buttons on your touch pad control strip, does the video scroll?

"Control Strip

The Control Strip, located at the right end of the Touch Bar, lets you use Siri or easily adjust common settings—just tap the buttons or, for settings like brightness and volume, quickly swipe left or right on the buttons. You can also expand the Control Strip to access more buttons.

• Expand the Control Strip: Tap .Depending on your Mac model and how you customize the Touch Bar, you can also press and hold the Fn key or the Globe key  on the keyboard to expand the Control Strip.
• Use Control Strip buttons: Tap the buttons to adjust settings or control video or music playback. For some settings—such as display brightness—you can touch and hold the button to change the setting.

• Collapse the Control Strip: Tap ."

If the issue persists, can you provide a few more details? Does this happen with any other apps?

Also, does the issue persist regardless of which video is playing?

Cheers!
