What's Wrong?

Long Running tasks in Claude Code (Terminal Window within VSCode) are showing what I can only describe as gibberish characters. What's happening? Who Knows.

I don't know if this is useful or not. But i have opened claude code in my vs code terminal in right side of the window. There was another terminal in the bottom of VS code running pnpm run dev, the gibberish is occurring in the pnpm terminal too.

Happens often very late into a session, multi-hours long sessions impacted.

Interesting!

Could you please set this in VSCode settings and try again? "terminal.integrated.gpuAcceleration": "off"

This is an upstream issue, not a Claude Code bug. Thank you!

Okay that does seem to make some improvements. Well done @diana-ant!
