I have a 3840x1600 monitor (LG 38UC99) and when running at 75Hz, display corruption is observed on both AMD GPUs I have, a Radeon Pro WX 5100 and Radeon RX 550. Fortunately, setting the power level to high makes the display corruption go away entirely, but also raises temperatures substantially. The idle temp on my WX 5100 gets up to 60 C by doing that. Is there a way to lower the clocks in the high performance state? I know some utilities like MSI Afterburner allow for this in Windows, but I'm not sure how to do it on Linux.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
