There are several known UI glitches in recent ComfyUI Frontend versions on Chrome/Chromium, especially around v1.39.x. These issues often happen even with all custom nodes disabled and usually don't produce console errors. Common causes include frontend regressions, Chrome-specific rendering bugs, browser extension conflicts (even if extensions are disabled for localhost), high-refresh-rate monitors, and hardware acceleration settings.

A major visual glitch affecting link (noodle) rendering in Vue nodes mode was recently fixed in a patch merged on 2026-02-03. This fix prevents links from briefly appearing in the wrong position during undo/redo or graph reconfiguration by suppressing link rendering until slot positions are fully synced, which improves visual consistency and eliminates misaligned links (details).

If you haven't already, update to the absolute latest frontend version to get this fix. If the issue persists, try these workarounds: fully disable all browser extensions (not just for localhost), clear your browser cache, reset Chrome font size to Medium, lower your monitor refresh rate, enable hardware acceleration, or try a different browser like Firefox or Edge. Chrome 143+ also resolves some GPU-related UI issues (example).

If you’re still seeing glitches after updating and trying these steps, sharing your Chrome version, monitor setup, and a description of the glitch (or confirming if it matches the fixed bug) will help narrow it down.
