Hello all, recently started using the GrapheneOS and so far I'm extremely satisfied with it. There is a minor "bug" that bothers me from time to time. Occasionally a part of the screen, a bar directly below the camera, starts flickering, showing something like "white noise". After some digging i found the "show refresh rate" option in the developer settings and when i switch it on the flickering stops. I also noticed that the affected area has the same height as the displayed numbers from the refresh rate option. Is anyone familiar with this or am i just unlucky?

I had to deal with the same error in a P8Pro. After a restart, the error was often gone, but then occured sporadically from time to time.
For me, it worked to set the screen resolution from "full" to "high" in Settings>Display>Screen resolution. With this (admittedly suboptimal workaround - I would prefer the higher screen resolution), the error has not occurred again for several weeks.
Murcielago I had to deal with the same error in a P8Pro.
Is it the same part of the screen?
Does it happen more in some apps?
Murcielago thank you!! I'm trying it now

In my case it always occurred in the status bar area. I tried several times - unfortunately without success - to determine the exact behavior that triggers the error. I couldn't pin it down to a specific app. Sometimes the error also occurred when I was in the system settings, for example.
I felt (but really only felt, I have no evidence for this) that the behavior was triggered when a quick change from light to dark occured on the display. For example if you have a light wallpaper and use an app with a dark theme and then swipe to the recently used apps and as a result, the screen suddenly becomes quite bright. I hope you understand roughly what I mean, it's hard to describe.
just to jump in, i do understand what you mean and I'm my case that triggers it as well, but it only ever starts (in my case) if i have dev options on. wherever i switch then off it's all good. I firmly believe (but have no evidence to back it up, apart from the fact that it occurred in the same area as the screen refresh rate counter) that there is some dev op feature that's "bleeding" through

Murcielago also i think the resolution change fixed it, it's been over an hour and no sign off it (usually happens quite frequent) so again, thank you
Murcielago I do not have such a option, screen resolution.
Perhaps this setting depends on the device. Which Pixel do you use?
Murcielago pixel 8
Did you check similar problems on youtube "pixel 8 screen issue"

I have a different model, so unfortunately I can't say anything specific about the settings for your particular device. If I'm interpreting this article correctly, this option only seems to be available on the Pro models:
While you may think of resolution as static, some Pixel phones - including the Pixel 8 Pro, Pixel 7 Pro and Pixel 6 Pro - actually let you scale your display's resolution to your needs.
Murcielago thank you, it would make sens why I cannot change it

peatme I can confirm that. The bug has not occurred for me for several days.

Unfortunately, I have to partially retract this post.
After some days the flickering at full resolution (Settings> Screen> Screen Resolution> Full resolution) shoes up again. Not as often as before and not as persistent, but it does occur from time to time. What helps (as before) is reducing the screen resolution.
