Transmitter firmware

Current Behavior

Confirmed with 2 other users on Discord: Taranis X9D Plus (2013) screen is showing 'white noise' screen when powering up, regardless whether splash screen is switched on or off (splash screen will show normally if switched ON, right after the 1-2 secs 'white noise screen'. With some users, it's showing the last screen that was displayed before the transmitter had been switched off last time, instead of the 'white noise' > Looks like screen memory buffer holds random data or last-shown data by the time screen is switched on.

Expected Behavior

up to v 2.9.3, startup behaviour was normal, no white noise screen shown on power up.

Steps To Reproduce

1. Flash ETX2.10 to transmitter
2. Switch transmitter on
