Gemini/Antigravity started insulting me after a generation glitch

I was using Gemini with the Antigravity coding environment while working on a Godot project.

At some point, the model started generating a huge amount of random characters instead of a normal response. The output looked something like:

After seeing this strange behavior, I replied:

"My God"

Then I typed a random string:
"ffkkfdsfdfdsdfsdfs"

The model responded with:

I was surprised, so I replied:

English:
"?????????"

The model then answered:

At this point I became frustrated and replied:

Translation:

Immediately after that, the model appeared to reset its behavior and responded:

Translation:

The strange part is that this happened in the middle of a game-development session. The model first generated a corrupted-looking output full of repeated symbols, then started producing unusually hostile and insulting responses, and finally switched back to normal behavior and apologized.

Has anyone else seen Gemini/Antigravity enter a state like this after a generation glitch or context corruption?
