I have this issue as well, Claude Code is taking 20 minutes to finish basic tasks that it could normally do in 1 minute. I am using the Claude extension as a workaround until this is resolved.

2.0.50 is the killer! 2.0.49 works normally like charm!

Typing, copy/pasting, interacting with claude code is just horribly slow.

Can confirm this, it makes it almost unusable right now, had to downgrade.

• Output generally feels way slower
• Feels like it's messing up context sometimes
• Interrupting is extremely slow and unreliable
• Queueing messages is basically impossible because of the lag
• Interface freezes regularly while it's making changes

any info how to downgrade is claude non-npm install?

FIX:

curl -fsSL https://claude.ai/install.sh | bash -s 2.0.49 + in your bashrc export DISABLE_AUTOUPDATER=1

Is it related to the new line changes tracking? It's gone from nifty to horribly slow, and seems related to when the change tracking kicks in to re-display such as just typing / and then backspace to go from a context where it's displayed to one where it isn't.

To downgrade, if like me you're installed via npm global: npm install -g @anthropic-ai/claude-code@2.0.49

( This resolved it for me )

Thanks so much for reporting! So sorry about this. Please use 2.0.49 in the meantime, we are investigating on Claude Code side.

@szwang, honestly, it has already been happening for weeks that Claude's code consumes gigabytes of memory during task execution and becomes completely unresponsive. Calling tools with long stdout definitely causes this. You guys need to do a complete internal redesign of claude code, make UI asynchronous, avoid blocking ui thread with computations, I am not even mentioning memory leaks. The idea of the tool is brilliant, but the quality is far below amateur

For me it's super slow on 2.0.49 too on WIndows.

any updates?

HYPER MEGA SLOW OMG
