Since the last update my ET8500 has had corrupted roundels (wait symbols), over the last week or so they've changed from corrupted circular dots to sheer white-noise patterns. Today I've upgraded my OpenVix firmware and they stayed the same after reboot. Powered off for 20 seconds and then were back to corrupted dots. Decided to power off for more time - 3-4 mins and are not back to normal (recognisable circular dots with background noise).
What's going on?
