Red lines on MacBook Pro screen after installing Ventura

I just installed Ventura. Both my MacBook Pro screen and my external monitor have a few horizontal red lines showing up on them.

Has any one else had this happen?

Have you found a fix?

Macbook M3 Pro Screen Glitching Hi! I have bought this device Oct 2023, It's a Macbook M3 Pro, 16 inch, with Sonoma 14.2.1 (23C71) I have been facing a problem regularly, the screen start glitching where some areas are replaced by colours, the the text disappears, some texts collides with other texts and it keep twitching, and some colours changes. I thought this might be a problem with my external monitor so I disconnected it and checked the built in screen, but the same issue persists, it worth mentioning that this happens every 2 weeks or something in that range. also the issue get fixed everytime when I restart the machine so most probably it's a software issue.

Mac Mini M2 Pro Vertical Flickering Lines issue Just got my mac mini last month immediately had issues with the flickering lines. Adjusted my monitor and seemed like it disappeared. Today I opened a app and on a green background section, I saw the vertical flickering lines again. Has this issue been fixed yet? I know it's been a constant issue for mac mini users.

Mac mini M2, problem with external display Hello, I have a problem with my external display Asus VX239. When I a using Mac, there are weird "stripes" showing up like screen sampling on old CRT TV. I tried to switch HDMI cables, use a thunderbolt to an HDMI adapter, and even replace a different monitor, but nothing changed. Honestly, I do not, if it is something wrong with the Mac mini or if it is a problem with the external monitor. Thank you in advice for help.

I have that issue too. At first, I thought it was Grammarly but turned off Grammarly and still had the red line. Shut down my computer for a few minutes, and it went away. This happened twice yesterday and once--so far--today.
