OSD only updates every 4 seconds in rendered video

[howels]

Is there an existing issue for this?

• I have searched the existing open and closed issues

Software version

dev (1044026)

What operating system are you using?

Ubuntu 24.04

What GPU are you using?

7900XTX

What problem did you encounter?

OS data shows correctly in preview and I can see second-by-second updates. However the rendered video only updates the UI every 4 seconds. I can see the timer counting 0,4,8,12 and nothing in between. Flight video is otherwise playing normally and perfectly smooth.
