This is an Engine Bug; it occurs in both Studio and Player.
Abstract:
Screen tearing is occuring with no obvious fix; reinstalling both Studio and Player do not fix the issue, nor does updating drivers or the operating system (as both of these are already up-to-date.)
The bug appears to have started around 2023-25-06 (YYYY-MM-DD,) but likely earlier. I do not think it correlated with a driver update.
Reproduction
Launch either Studio or Player with a computer using Intel® Iris® Xe Graphics, and screen tearing will be visible, more such in Studio. In this scenario, Studio is running at 60fps (occasionally 61 or 59,) which matches that of my display.
System info:
CPU: 12th Gen Intel® Core™ i5-1235U
GPU: Intel® Iris® Xe Graphics (Driver version 31.0.101.4146)
RAM: 8GB
Operating System: Windows 11 22H2 (Version 2261.1992)

Do you happen to have VSync overridden in a driver setting? We normally use VSync which prevents screen tearing, but drivers allow you to override this sometimes.

I’ve only just noticed these options. In Intel’s neverending wisdom, they’ve been forced off (as indicated by the greyed-out buttons) with no explanation as to why; I’m taking an assumption that V-Sync isn’t being overridden by the driver.

Can you attach a microprofiler dump (Using MicroProfiler | Documentation - Roblox Creator Hub)? That would give us some insight at what framerate the renderer is going. And also if you have some information about what the display is (make/model and update frequency) that could help.

The dump generated by the micro-profiler can be accessed here. Apologies for the Google Drive link; the file exceeded the 10MB size limit for the Developer Forum.
My display is a SAMSUNG 32" T4307 television, and its screen, when connected to my laptop, is clocked at 60hz progressive scan.

Apologies for the late reply.
Thank you so much for attaching the microprofiler capture. We are continuing to look into this, but it spans multiple areas… from replication to http cache to rendering.
