RTLSDR v4 mixing signals to wrong frequencies in SDR++

I got the new v4 RTL-SDR and followed the installation instructions to install the custom v4 driver, but when I use it, signals are not where they are supposed to be. I'm using newest SDR++ built from source. Debian 12 arm64. Anyone come across this issue? I imagine this is the performance that happens when v4 is used with the v3 driver. Is there any way to verify which version of the driver SDR++ is using?
