Plugin Lag

[Doomelf]

While the plugin is enabled, it creates lag. Enabling or disabling settings doesn't change that.

Yeah, everything lags terribly on macOS, especially text input.

Discord freezes for 5-10 seconds when typing anything with shift for me. Capital letter, symbol, etc. v12.3.4. Win10

True on Windows OS too. The Shift key does seem to be the trigger.

Here's a temporary fix done by Claude until the dev updates the plugin.
CollapsibleUITEMPFIX.plugin.js

1. requestAnimationFrame throttle on mousemove
   The four tick* functions now only fire once per rendered frame (~60fps) instead of on every raw mouse event. A flag (runtime.rafPending) prevents queueing multiple RAF callbacks per frame. The mouse coords are captured immediately in the raw event so they stay accurate.
2. Cache elements.index before the loop in tickExpandOnHover
   const elIndex = elements.index is called once. This brings querySelector calls from 121 down to 11 for the element array alone. All other hot settings values (fudge, doFloat, sizeCol, etc.) are also snapshotted before the loop.
3. Hoist biteSizePanel, rightClickMenu, forumPreviewTooltip, expressionPicker out of the loop
   These were querySelector calls firing 11× per frame inside the loop — now resolved once before it.
4. Cache element lookups in the other tick functions
   tickCollapseSettings, tickMessageInputCollapse, and tickCollapseToolbar each called elements.* getters (querySelector) multiple times per invocation. These are now each resolved to a local variable once.

that temp fix slightly lessened, but didn't fix the lag with using the shift key.

Bump.

This plugin really needs an update because it is extremely laggy.

All I need from this plugin is the ability to hide channels and members panels and show them on hover. I asked Codex to write me a different script. Maybe someone else will find it useful.

Thanks for the alternative! I'd say it's a lot less polished than CollapsibleUI, but in it's current state, much more usable considering the lag.

Decided to actually use my brain and just fix the plugin after some profiling. It now works without any lag like before, the scan implementation is basically instant, the biggest delay that I couldn't optimise further is for the channel list at 100ms, with 28 other plugins and a theme and custom css loaded on my install. The shift key lag is also fixed now, there's a minimal amount of lag created by Discord's sentry that's there by default, nothing to do with this plugin. Making a pr soon.

@MaixGit Works great, thanks!
