What the F&*() have you done to my wires?

Hi @Steve_Digre, sorry for the trouble! GPUs have known bugs and may cause rendering glitches/blur when using Figma. Please reach out to the support team directly here for help: https://help.figma.com/hc/en-us/requests/new with a copy of your file to check if we can replicate it.
We also recommend you to check the Figma browser requirements here: https://help.figma.com/hc/en-us/articles/360039827194-Figma-browser-requirements#unsupported
