Describe the bug
A clear and concise description of what the bug is.
it's just colored dots like a GPU with Failing Vram, it looks like white dots on a black background with some green pixels on the top and touch or changes in anything on the screen change the random patterns i see in scrcpy.

On errors, please provide the output of the console (and adb logcat if relevant).

Probably an encoder issue on the device.

1. Try with another encoder.

2. Try with a lower resolution (scrcpy -m1024)

3. Try to record (scrcpy --record=file.mp4) and play the file with some player (VLC), is the result ok?

4. Try to record the screen using:

   adb screenrecord /sdcard/file.mp4
   adb pull /sdcard/file.mp4
   

   Is the result ok?

the phone only has h264 available and yes adb screenrecord does work scrcpy --record=file.mp4 does not, it's also not why i want or do use scrcpy for. i also tried with lower refreshrates, bitrates and resolutions and all resulted in the same issue.
i also have used scrcpy on other phones like a Pixel 6 Pro, Redmi Note 10, Volla Phone 22, Pinephone (GD DROID), Samsung Galaxy A50, LG G4c, LG G4, LG G8S, fire TV stick, Android TV and a Medion tablet and all of them worked very well.
