XFCE font resets size every reboot

I'm running EndeavourOS with XFCE4. I ran the installer for NVIDIA GPUs which installs drivers afaik. I have the same issue described in this question: https://unix.stackexchange.com/questions/362282/how-can-i-fix-the-font-size-in-xfce-after-installing-a-proprietary-graphic-drive The solution works for me (changing AA or DPI setting and then changing it back). However I have to do this every time I reboot because the error reappears. How can I apply this fix automatically on boot?
