Can confirm this in 1.18.1. Here's a code analysis of this issue.
Code Analysis:
The following is based on a decompiled version of Minecraft 1.18.1 using MCP-Reborn.
net.minecraft.client.gui.Gui.java
public class Gui extends GuiComponent {
...
public void render(PoseStack $ps, float $f) {
...
float f2 = Mth.lerp(p_93032_, this.minecraft.player.oPortalTime, this.minecraft.player.portalTime);
if (f2 > 0.0F && !this.minecraft.player.hasEffect(MobEffects.CONFUSION)) {
this.renderPortalOverlay(f2);
}
...If we look at the above class, we can see that the code specifically checks to see whether or not the player has the CONFUSION (nausea) effect, before rendering the nether portal overlay to the client. In other words, this means that if the player has the nausea effect, the portal overlay won't be rendered to them.
