AMD’s newest Adrenalin Edition 26.5.1 WHQL driver is breaking Blender 5.1.1 for users who rely on the Cycles path‑tracing engine. Crash reports surfaced on the Blender issue tracker after the driver update, pinpointing a failure when the render backend attempts to load ROCm 7 kernels. The incompatibility stems from a mismatch between the driver’s ROCm runtime and Blender’s compiled expectations on Windows 10/11 rigs.

Blender 5.1.1 ships with ROCm 6 libraries, while the 26.5.1 package only includes ROCm 7 components. Developer Sahar A. Kashi from AMD’s ecosystem confirmed that a factory reset during a clean install process removes amdhip64_6.dll, forcing Cycles to request the newer runtime it cannot handle. Multiple users have reproduced the crash, confirming the root cause lies in the ROCm version disparity.

The practical fix for affected artists is to roll back to the prior 26.4.1 driver until Blender 5.2 arrives with full ROCm 7 support. Until then, professional studios and hobbyists alike must maintain the older stack to keep Cycles stable. This episode underscores how tightly coupled GPU drivers and compute libraries have become across major DCC applications today.
