Random stalling on Arch Linux

When opening link or any other action Mullvad browser randomly freezes for a few seconds, especially after a hibernation or when system logged you out for an inactivity. System Artix Linux 6.6.7, Wayland KDE, installed using AUR (BTW, there is still a button "restart browser" even after updating to the newest version 13.0.7 through AUR). I have to do full system restart in order to fix this issue. (...) I have experienced the same freezing when testing alpha. What is weird the freezing appears to occur at the same time... like some other underlying process causing it.
