Extension Windows Distorted

Since updating to 21.1.279 I am having an issue with extension windows appearing distorted on my secondary monitor. They look fine on my laptop screen. The main SU window also looks good. Just the extension windows. I have a Quadro T2000 graphics card and it is running the latest drivers. I do not have this issue with SU2020. The second monitor is connected via HDMI directly to the laptop. Thanks in advance for any help!
