Weird flickering on blocks

Strange visual flickering/shimmering on most blocks, most notably on grass snow or ice. Recently started occurring after upgrading PC. Doesn't seem to be a display hardware bug as it only happens when playing Minecraft.

Have tried:

• Changing graphics settings
• Using Optifine or Sodium
• Changing Nvidea Control Panel settings
• Changing Minecraft versions
• Changing Monitor
• Updating Drivers
• Updating/Changing version of Java (8, 17, 21)
• Entirely Reinstalling Minecraft
