How to unbreak Dolphin on SteamOS after the QT6 update

Published on 03/03/2024, 56 words, 1 minutes to read

A recent update to Dolphin made it switch to QT6. This makes it crash with this error or something like it:

dolphin-emu: symbol lookup error: dolphin-emu: undefined symbol: _Zls6QDebugRK11QDockWidget, version Qt_6

This is fixed by running this command in SteamOS:

flatpak update --commit=44bfa315a0cf9c94a97dfe61127dc05e0e8c85c5c7559dc7665529ec1aa7a3ee org.DolphinEmu.dolphin-emu

This will downgrade Dolphin so things work again.
