The patch is under AMD internal review and is not submitted to upstream yet. [Test] 1. Boot in OS 2. Idel the machine for a while (~1 min) and move the cursor. 3. There should not have any graphic glitch when using the machine. [Where problems could occur] This is a quirk for a specific panel, so should be pretty safe.
