Program Monitor

Does the issue clear up if you close the Essential Graphics panel? I've seen this issue inconsistently from other users and wondering if it is affecting you too.

Thanks,

If that doesn't work, try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. 

If that doesn't work, try creating a new project and import the old one into it.

Hi Robert1031a,

Sorry to hear about this. Is this happening with specific projects or all of them? Also, let us know the system specs (OS, CPU, GPU & RAM).

Thanks,

Sumeet
