Maybe a RetroArch bug?

Not sure, most likely there's a change in behavior (if this configuration worked before) in a more recent version. The render resolution option in the runcommand launch menu it's not something that's often used - probably people just change the emulator's resolution to do a resolution change.

I can try and see which setting is at stake, but as a workaround you can manually edit the retroarch.cfg (instead of using Save Configuration from the RGUI) and add autosave_interval=900. For the hotkey change, you can edit your gamepad mapping, saved in \\retropie\configs\all\retroarch-joypads, and switch the hotkey from Select to other button.
