A ring of the writes the GPU emulation makes to guest memory (fences, WriteData, everything through TryWriteBacking: buffer and image downloads), with a scan for the qword found in the corrupted heap free list (0x0000005300000000). On a guest fault the registers and the logged writes near them are printed. With the log on, a 20 min run did not hit the fault. Co-Authored-By: Claude Opus 5.5 <[email protected]>
