I have just finised upgrading my custom rom from 13 to 14, went mostly smooth apart from some strange problems with display size/shape, i have a 10inch touch screen 2560x1600 and it was working perfect on android 13 but on 14 the system doesnt pick up the native display res, it thinks its 2560x1080, this also leads to some distortion, where all the icons are too tall(should be sqaure but are now rectangle), if i try to set the display size with adb i end up having to do somign like adb shell wm size 7000x1600 to get the image to take up the whoel screen
I saw another post about the white list file so ill try that now, i was seeing if chat could help and its ides was to add this to the dtsi file the display is using, im not sure this is correct but lookign at the logs the system complains about not having 198000000 defined.
Im not sure if any of thsi will help, im about to test it but wanted to post here incase i cant fix this my self.
