Osnap's yellow cursor is flashing during mouse movement

[Anonymous]

Hello,

Since the installation of Windows 10 Pro and AutoCAD 2020 the osnap's yellow cursor is flashing during mouse movement making the snaps imprecise. On Windows 7 Pro and AutoCAD 2018 I did not have this problem.

Win7 is not Win10, R2018 is not R2020. No point in comparing them all.

You need to ensure you have the 2020.1 update installed, and if that does not help, you might need to turn off LINEFADING and LINESMOOTHING in R2020, and maybe even change your setting for hardware acceleration in GRAPHICSCONIG command.

Hello @Anonymous,  

Thanks for posting sorry to hear this. I have listed some more helpful steps you can take to correct the issue. 

1. Check the Operating System needed & the required updates by reviewing the system requirements for the software & Certified Graphics Card Drivers
2. Make sure you have an updated graphics card driver by checking the manufacturer's website
3. Then assign the correct Graphics Card  to run with the application

Hi

None of these solutions solve the problem.

The yellow osnap cursor continues to flash making it hazardous the line snap, snap nearby the end point for exemple.

Hello @Anonymous, 

You said this occurred right after the Windows 10 update was applied. Have you tried to uninstall or rollback the update for Windows?  You can always re-install at a later date, you may have had a bad install of the update.

It was after a clean installation of Windows 10 Pro that the problem appeared.

Hello @Anonymous, 

It's very possible that the Window 10 update was not properly applied or the installation produced errors? Have you reviewed >Event Viewer<  try taking a look for any errors during or right after your new Windows 10 Pro install. I would verify that the install of your Windows 10 Pro was flawless.

I would then move on to re-installing AutoCAD 2020 using the steps outlined here.

Hi Sebastien,

Having hardware acceleration turned off may cause the cursor looking flashing.  Can you run GRAPHICSCOFIG command and make sure hardware acceleration is turned on?   If hardware acceleration is not available, make sure your video card driver is correctly installed.

If it doesn't solve the issue, could you post a screencast so that we can make sure we understand the problem correctly?

Bonjour,

hardware acceleration is turned on.

The problem is only on AutoCAD 2020, I tested on AutoCAD 2018 and I do not have this problem.

On AutoCAD 2018 the yellow cursor osnap flash a little but the snap works correctly, on AutoCAD 2020 the yellow osnap cursor flashes and acts on / off really quickly and if I click at the wrong moment the click of a line on an end point for example click near the endpoint.

APERTURE command: <20>

And it's the yellow osnap cursor blinking, not the main white cursor.

As mentioned earlier, the fact that 2018 does not exhibit this problem has no bearing on whether 2020 does or not. Perhaps 2020 has greater system requirements, such as a display adapter that was certified for 2018/Win7 may not be certified for 2020/Win10. Have you checked that out?

Have you tried logging on to the PC as different (and new) Windows user to see if this is isolated to your user account?
