, graphics driver conflicts can cause flickering that disappears entirely with the next patch.<\/span><\/p>\r\nIf the flickering started right after you updated macOS, or only happens in specific apps, software is a strong candidate before you start worrying about hardware.<\/span><\/p>\r\n\r\n- \r\n
<\/span>The T-Con Board<\/b><\/span><\/span><\/h3>\r\n<\/li>\r\n<\/ul>\r\nThe T-Con (Timing Controller) board processes the video signal between the logic board and your LCD panel. A failing T-Con board on <\/span>MacBook Pro and MacBook Air models from 2018\u20132022<\/b> frequently causes horizontal lines, colour banding, and screen flickering that gets progressively worse over time. It requires a display assembly repair.<\/span><\/p>\r\n\r\n- \r\n
<\/span>Overheating<\/b><\/span><\/span><\/h3>\r\n<\/li>\r\n<\/ul>\r\nIn some cases, thermal stress on the display components can trigger intermittent MacBook screen glitching. This is more common in older models where the thermal paste has dried out, or when the internal fans are blocked or failing.<\/span><\/p>\r\n\r\n- \r\n
<\/span>Physical Damage or Pressure<\/b><\/span><\/span><\/h3>\r\n<\/li>\r\n<\/ul>\r\nA drop, a heavy bag pressing against a partially closed lid, or debris caught between the keyboard and screen can create pressure on the display panel or internal connectors. This can start showing up as flickering, lines, or discolouration even without any visible cracks.<\/span><\/p>\r\n<\/span>Troubleshooting <\/b>Mac Screen Flickering <\/b>at Home<\/b><\/span><\/span><\/h2>\r\nThese steps are quick, safe, and worth doing before visiting a professional service centre.\u00a0<\/span><\/p>\r\n<\/span>Step 1 \u2014 Restart Your MacBook<\/b><\/span><\/span><\/h3>\r\nA cold restart clears temporary software states and GPU memory. After restarting, check whether the flickering is still there. If it’s gone, you likely had a temporary software glitch.<\/span><\/p>\r\n<\/span>Step 2 \u2014 Update macOS<\/b><\/span><\/span><\/h3>\r\nGo to <\/span>Apple Menu \u2192 System Settings \u2192 General \u2192 Software Update<\/b>. Running an outdated version of macOS is a known cause of display driver conflicts and screen flickering \u2014 especially on Ventura and Sonoma builds right after major releases.<\/span><\/p>\r\n<\/span>Step 3 \u2014 Disable Automatic Graphics Switching (Intel MacBooks only)<\/b><\/span><\/span><\/h3>\r\nOn Intel MacBook Pros with dual graphics, macOS automatically switches between the integrated and discrete GPU. This switch can sometimes cause a brief flicker that becomes more frequent over time.<\/span><\/p>\r\nGo to <\/span>Apple Menu \u2192 System Settings \u2192 Battery<\/b> and turn off <\/span>Automatic Graphics Switching<\/b>. This forces the MacBook to use one GPU consistently.<\/span><\/p>\r\n
