ERROR_GRAPHICS_CANT_RENDER_LOCKED_ALLOCATION
ERROR_GRAPHICS_CANT_RENDER_LOCKED_ALLOCATION (0xC0262111) means the command buffer referenced an allocation that was still locked. A resource cannot be rendered from while an incompatible lock or map is active.
What to check
- Complete the matching unlock or unmap before submitting commands that render from the resource.
- Check CPU/GPU synchronization so a resource is not both mapped for CPU access and bound for rendering at the same time.
- Audit error paths to ensure locks are released even when an earlier operation fails.
Useful command
