Blank Mirroring on MOST of ONE Applications, OK for other Apps

[dbareis]

Describe the bug
I have never seen this on any other application, on the "Woolworths Money" app most of the screens are blank/black. After searching for a similar issue I found one that asked if that shows up in the recording, it does (attached).

I can interact with the app on phone and computer but obviously I can't see what I'm doing on the computer. I can also paste from windows 11 into entry fields I have selected on the phone.

Also for the last few releases (and pretty sure also Windows 10), I get error re: "stay_on_while_plugged_in" in below debug

Blank.Mirroring.on.MOST.of.ONE.Applications.OK.for.other.Apps.mp4

For the blank/black screen, the app requested the "secure flag" to prevent mirroring (#36) and this is enforced even for shell since Android 12 (#2129).

For the settings error, the command on the device fails for some reason:

adb shell settings get global stay_on_while_plugged_in
adb shell settings put global stay_on_while_plugged_in 7

I can confirm that screen capture is disabled for this app, interesting even my banking app doesn't do that!

@rom1v
I think it should say this for "--stay-awake" in --help output and any other doco. Also in the console output if it can tell.

Use smalipatcher to patch your secure flag and should be fine, ive not tested all apps but the ones i was having problems with are worked round this way

Thanks, I don't care much for that app but will keep that in mind if it effects and important app :-)
