Thanks for the update. Since the issue returned after a week of normal operation, this points to a deeper GPU rendering problem that needs investigation.
Please check whether any updates occurred:
Did Windows update in the past week?
Did AMD drivers auto-update? Check the version in Device Manager
If Cursor launches with --disable-gpu, please share:
Cursor version (Menu → About Cursor)
Exact Windows version (Settings → System → About)
AMD Radeon driver version (Device Manager → Display adapters)

The --disable-gpu flag can be a temporary workaround, but we need to understand why GPU rendering is failing with AMD Radeon.
