Flicker Changing Resolutions on a CRT (Solved)

I'm experiencing a brief flicker when the resolution changes, even though I'm using VGA -> CRT. The flicker goes away if I set vsync_adjust to 0, but trading a flicker for an extra frame of lag is hardly ideal. vga_scaler is set to 0.
A simple way to replicate it is opening and closing the menu in Final Fantasy VII.
My real PS2 has no flicker in the same situation.
Is this considered a bug?

Correct me if I'm wrong but I think vsync_adjust should not affect image of the analog board when vga_scaler is 0
Paste the ini. FF7 pal or ntsc?

You don't get any delay on VGA out when setting vsync adjust to 0, it's just for HDMI/scaler.
There is currently a situation where there is additional stress on the HPS/Linux when using vsync adjust 1+2 and the resolution changes, which will eventually be resolved.
Until then, best to stick with vsync adjust 0 for the PSX core.

This was my understanding as well, but I tried with it on and with it off and there was indeed a difference.
