Short description of error

After performing a " File->Save ", the file drop down menu lingers and flashes on/off until I move the cursor off Blender and/or click somewhere else on screen. I cannot go back to file menu and have it function until I close the flickering drop down menu.

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

Its highly likely that this bug is specific to your hardware/driver configuration.
These kinds of display issues are often caused by OpenGL driver bugs.

While its possible a software error in Blender, its worth checking if this functions correctly...

  • After upgrading graphics card drivers.
  • On a different system (with different hardware/drivers).
  • Using a Software OpenGL renderer...
    • On Linux/macOS, Official releases come with blender-softwaregl
    • On MS-Windows: Downloading 'opengl32.dll' from and copying it so its located in the same directory as 'blender.exe'

If this is a driver bug, or we can't link to this to an error in Blender's code, the report may be closed as a driver error,
so please help us determine whether this is a bug in Blender or not.
