Artifacts with move command AutoCAD LT for Mac 2021

[swong20]

I'm having an issue when I use a basic move command in ACAD LT for Mac 2021. Fat pixels are left in the original place and some fat pixels show up in the new location. The fat pixels go away if I zoom in or out. I opened the same file in ACAD LT MAC 2020 and it doesn't happen there. This happens on my laptop only, not the desktop using 2021. I am using a 2020 16" MacBook Pro; 2.6 GHz 6-Core Intel Core i7; 16GB Ram; AMD Radeon Pro 5300M 4 GB; Intel UHD Graphics 630 1536 MB. I've turned hardware and software acceleration on and off and there is no difference. For now, I'm just using 2020 when on the laptop. Any ideas? ACAD is updated.Object to moveObject moved

Hi @swong20,

It is knowing problem with AutoCAD 2021 for Mac on 16" MacBook Pro with AMD graphics card after macOS 10.15.4 update.
As workaround you can change graphics engine from Metal to OpenGL in AutoCAD Preferences:
