Can anyone help? It has anoying black lines around the monitor.
Go to Window>Preferences>OpenGL and turn off Hardware acceleration. Does that change anything?
Radeon cards seem to have a difficult time with OpenGL. You can do a search here and see that many others have had similar issues.
Try upgrading the graphics drivers. It may help. It may not.
Thank you so much! Turning hardaware acceleration off fixed it.
That doesn’t actually fix it, it highlights that your Graphic card isn’t working fully with OpenGl.
Check if there is a driver update for your card.
