some ideas for you, if you are still trying to use the master... I guess that you are reaching the performance limit somehow. Might be due to driver interrupt activity choking the CPU. (And the reason may well be wifi performance limitations made to master in March, but which limits are not in 17.01.) You might monitor CPU load with "top" while you have video problems. Likely SIRQ load is at 100%.
Some ideas that might mitigate the problem:
- All interrupts in R7800 get assigned to CPU core0 by default, so wifi, lan and usb drivers all run in core0. If you are hitting the performance limits due to I/O activity, you might try balancing the IRQs between core0 and core1 with "irqbalance" package. Discussion about that starting from Netgear R7800 exploration (IPQ8065, QCA9984)
- Or assign IRQs manually. e.g. like in Netgear R7800 exploration (IPQ8065, QCA9984)
- You might also test the shortcut-fast-path "fast NAT" engine that should work also for R7800 (as the patch author @dissent1 uses it): Qualcomm Fast Path For LEDE
