@as975889 ,

Welcome to the AutoCAD forum.

Provide a visual image of the issue.

In the meantime, try to "Restore classic colors" from the Options...

Have you installed the 2024.1.2 Update yet? ABOUT command in your AutoCAD will confirm what you have installed. If not, get it from your Autodesk Account Page here https://manage.autodesk.com/cep/#products-services/updates
Restart your PC afterwards.

If that did not help... Set GFXDX12 variable to 0 (that's a zero) then restart AutoCAD2024.

If still no relief then start GRAPHICSCONFIG command and change the 2D Display Settings pulldown from "advanced mode" to one of the other choices.

If all else fails, then turn off Hardware Acceleration as a last resort, and start a support ticket through your subscription portal as explained here

1. Graphics Card Settings:

   • It appears that AutoCAD might be using the incorrect graphics card. To resolve this:
     • Check your computer’s graphics card settings.
     • Ensure that AutoCAD is set to always use the high-performance graphics card.
     • This adjustment should help resolve the color issue.

2. Color Settings:

   • Sometimes, objects are drawn with a specific color instead of following the layer color. To fix this:
     • In the Home tab of the Ribbon, change the color (shown as a color wheel) to ByLayer.
     • Alternatively, use the COLOR command and set the color to ByLayer.

3. Video Drivers and Hardware:

   • Incorrect video drivers or hardware issues can cause color display problems. Consider the following:
     • Check if there are any issues with your video drivers.
     • Verify that the cable connecting your workstation’s video board to the monitor is secure.
     • Ensure that the option for “Display plot styles” is enabled in your page setup.

4. Invisible Line and Cursor Display Issue:

   • Check the variable DRAGMODE. Make sure it is set to AUTO.
