How do you take an individual log like u took only of flickering screen ?

Not really an individual but more of a short log where I start capturing log then reproduce the error, once reproduced I stop the capturing of log.

For syslog there are other logs involved like kernel etc. Best for testing beta ROM s

Added logcat about flickering screen. Not sure if it will capture it but I'll post it here anyways. Hope this help.

I could use syslog if you want a full logs with kernel, etc.
Can you try face filter apps like messenger and Snapchat if they also have flickering screen? I have those issue but I can't seem to use logcat.

Yeah didn't noticed it since I don't use it but screen got this black flickering when you start filters on FB Messenger.

To OP,
Screen filter seems to vanish the flickering bug when an overlay app is opened. For example when you start DU recording, a floating icon is present then the flickering stops. Same when you start to record screen the flickering stops. Not sure if this helps.

This flickering issue also happens on different roms like Arrow os, Pixel experience and also superior os. Hope they can fix this because flickering bug also occurs on Dolphin Wii Emulator. Screen is so flickery and cant play properly on games like resident evil 4 and other Wii games.

I have done a mistake. I have flashed Vilte zip of max pro m1 in max pro m2 by mistake and now sim is not detected by my device maybe because of some modem issue. Please help what to do.

I wanted to report a bug.
In in the Interface option, the option to turn on Automatic Switching (based on time of day) for the phone theme from Light to Dark does not work.
Also, the Updater for the ROM does not seem to work either.
Please would you look into it?

Does this ROM have lower minimum brightness than other ROMs? Thought it has its own kernel so might have that... because every night I cry :( and pray for some angel developer to drop a custom ROM that has very low minimum brightness.
