SteamVR™ may experience an application crash when a VR headset is connected on Radeon RX 500 series graphics products. Some high refresh rate, high resolution TV displays may experience corruption when connected via HDMI on Radeon RX 6000 series graphics products. Applying changes in Radeon Performance Tuning may sometimes fail to take effect for changes made to power tuning. Lower than expected performance may be experienced in some CPU intensive workloads or games. Global performance tuning overclock profiles may sometimes override game specific performance tuning profiles or cause game specific performance tuning profiles to fail to load on a games launch. Radeon Chill may experience lower than expected performance when a game is left idle for an extended period with Radeon Chill enabled. Flickering may be observed in Radeon Software performance overlay while playing Cyberpunk 2077™ on Radeon RX 6000 series graphics products. Per-game color profiles may retain on desktop if a game with a custom color profile is launched and closed immediately afterwards. Known Issues Enhanced Sync may cause a black screen to occur when enabled on some games and system configurations. Any users who may be experiencing issues with Enhanced Sync enabled should disable it as a temporary workaround. Connecting two displays with large differences in resolution/refresh rates may cause flickering on Radeon RX Vega series graphics products.

Radeon FreeSync™ may intermittently become locked while on desktop after performing task switching between extended and primary displays upon closing a game, causing poor performance or stuttering. A system restart is a potential workaround if this is experienced. Performance metrics may incorrectly report temperatures on Ryzen™ 5 1600 series processors. The download or launch Ryzen Master buttons in Radeon Software may intermittently disappear or may fail to initialize Ryzen Master. If Ryzen Master is not detected in Adrenalin software after installation, a system restart maybe required.
