We have recently been receiving reports from students and faculty who are having trouble editing their UVs in Maya. The problem occurs when the UV editor is open and the UVs are selected. Sometimes, the move tool will not update the UVs or the UV vertexes will move, but the edges will not. Other times, the UVs are merely slow and erratic.
If you have experienced any of the aforementioned problems, the following should fix the error:
1. Close Maya if it is open.
2. Right click on Desktop > choose NVIDIA Control Panel > choose Advanced Settings > choose Manage 3D Settings > choose "Maya Autodesk" from the profile drop-down menu > click Apply.
If that does not fix the problem, please submit a problem report and we will look into it further.
