I have the same card (RTL8822BE [10ec:b822] Subsystem [103c:831b]), but I got the same TX power for all following kernels:
* 5.3.18-050318-generic * 5.4.0-39-generic * 5.6.0-1017-oem * 5.8.0-050800-generic
Could you specify the steps you took, the output of `iw dev <devname> info`? Will anything change when you do `iw dev <devname> set txpower auto`? and `iw dev <devname> set txpower fixed N`, where N is the txpower at 5.3 kernel?
