Hi Maaz, hi Zack, Just a gentle ping on this one. Maaz, did the investigation into your bricked testing VM turn up anything in the meantime? Meanwhile I've done more testing on my side. I applied this fix on top of mainline 7.3 and the cursor works correctly again: Host: VMware Fusion 26.0.1 on macOS 26.7.1 (x86_64) Guest: Kylin Linux Advanced Server V10 (Halberd) Kernel: 7.3 + this patch Before the patch, every cursor update was rejected with -EINVAL because SVGA_REG_CURSOR_MAX_DIMENSION reads back 0 on this setup; with the patch applied, cursor updates go through normally again. 3D acceleration is disabled in the VM settings. So far I haven't been able to reproduce the failure you reported. If you can share your test environment (hypervisor product and version, host OS, guest kernel, 3D acceleration on/off) and the failure symptoms (boot hang vs. cursor path only), I'd like to narrow down what's different between our setups. And if the conclusion is that treating 0 as "unset" with the current fallback isn't the right fix, I'm happy to rework it as a v5. Thanks, fausten
