Graphical Artifacts Appearing on macOS Sequoia 15.5 (M3 Max MacBook Pro)

I’m experiencing a recurring visual issue on my MacBook Pro with the M3 Max chip, currently running macOS Sequoia 15.5. I’m seeing a pattern of small dots or pixel-like artifacts that form vertical or horizontal lines on the screen. These artifacts move along with windows or UI elements, which suggests the issue is software-related and not a hardware defect.

I’ve attached a screenshot where you can see the dots. They are not visible in screenshots taken with macOS, but they do appear in screen recordings or external photos of the display, further confirming it’s a GPU or rendering issue.
