Weird visual bug where Wraith, Dynamo, and Grey Talon character effects are persisting on other character models and the characters are all oversaturated which is probably a lighting issue?? /shrug DxDiag shared here for system specs if it matters.
The GPU drivers you have are a few months old at this point, try updating them first. The shader cache should automatically be rebuilt when updating the drivers as well.
Forgot to mention, between major version updates of drivers or if an issue persists, use Display Driver Uninstaller (DDU). It removes traces of the drivers that a normal uninstall may not catch. All of the GPU settings within the driver will be reset to defaults when the new version is installed via this method.
