ERROR_GRAPHICS_INSUFFICIENT_DMA_BUFFER

ERROR_GRAPHICS_INSUFFICIENT_DMA_BUFFER (0xC0262001) indicates that the display-driver stack could not fit the requested command work into the available DMA buffer space. This is primarily a driver or graphics-kernel scheduling condition.

What to check

For driver development, reduce or split the work submitted in one DMA buffer and inspect the driver path that builds the command stream.
For an application or end user, collect the exact driver version and System log evidence before changing hardware or software.
Install a matching supported display-driver package as a package; do not copy individual kernel or user-mode graphics DLLs.
