The following are the limitations:

**Qualcomm Linux 1.7**

- Glmark2/VKMark perf drop has been observed with off-screen use case, no deviations with system use case.
- Issue observed during video playback where the stream dynamically shifts between 720p and 4K (4096-wide) resolutions while being decoded using H.264 at 30 fps.
- Boot-up failure observed with UEFI secure boot enabled.

**QCS6490/QCS5430:**

- Camera stream is not starting for the OV9282 sensor in BPS mode for the 5 MIPI concurrency BPS Mode use case (3 IMX577+ 2 OV9282).
- It has been distorted frames observed for EIS and LDC concurrency use cases.
- Failure with sound card detection on QCS5430

**IQ8**:

- Apps suspend feature not enabled.

**IQ9:**

- USB peripherals not enumerating on Type-C ports on resume after suspend use case.
- Observed Segmentation fault during 32/24-Multi stream only with object detection use case.
- Secure camera, ML use cases failure observed.
- BT over USB has failure observed using the NFA765 m.2 card, there is no issue with NFA765A
