Same here. RPI5 OS15. HDMI blinks, usually when touching the screen but also when screen changes.
Checked on several devices, several TVs, problem remains...

i am using EmteriaOS on a raspberry pi 5 but whenever i click a text box and the blinking cursor appears the screen goes black
if i stop moving the mouse do the opposite and shake it vigorously the screen shows up.
Also i noticed if there is too much lag in games (i.e. Minecraft) the screen goes black as well.

i am using HDMI port 0 with a 100Hz refresh monitor.

can anyone help fix this...

I would like to also add we are having this problem with android 15 as well on our pi5. seems the system is doing refresh rate changes. Our screen keeps popping up 4k 24hz instead of the original 4k 60hz it booted up in. every time we are clicking it keeps cycling the screen display. Will switch to A14 and see if that has any issues for us.

@HellBornHacker Android 15 is still under development. Currently, a quick fix would be reducing the resolution.

Hi @mcfoi - I've also tried to get the USB debugging working with no luck. I've since figured out how to get the WiFi debugging running using the "adb pair" + "adb connect" commands from the Android Development Studio. Was relatively straightforward - found a few guides on how to do this online. Just had to pull my laptop off the ethernet cable and put it on the same WiFi network as the Raspberry Pi. Debugging on WiFi is probably just as fast as USB debugging. I can't tell any difference when I'm deploying / debugging code.

@mcfoi I have never tested it myself but you would probably need to load a different USB driver like we do for the CM modules. On the other hand, RPi5 needs a more powerful power supply to work properly maybe this is related too.
