Oh, is that what the issue is? I've seen the "flicker" thing as a meme, but as someone who uses Claude Code I've never noticed. I use ghostty mostly, so maybe it's not an issue with ghostty? Or maybe I just haven't noticed it.
And even in VS Code, it wonks out after a while.
My guess is that it mostly works on Apple devices.
kilocode runs fine. opencode runs fine. qwen code runs fine. what exactly is Claude code doing that requires so much power? I'm sorry but it sounds like you're speaking from the wrong end.
