## Summary - Move `contain-layout contain-style` from the outer node container to the inner wrapper to prevent CSS containment from interfering with inter-node compositing - Add `isolation: isolate` to the outer container for explicit stacking context isolation - Fixes #9988 ## Root Cause Originally, PR [#5169](https://github.com/Comfy-Org/ComfyUI_frontend/pull/5169) (`57db10f`, 2025-08-23) applied all three containment properties to the outer node container: ``` contain-layout contain-style contain-paint ``` `contain-paint` ensured each node's painting was clipped to its own boundaries, guaranteeing render isolation between sibling nodes. Later, PR [#6289](https://github.com/Comfy-Org/ComfyUI_frontend/pull/6289) (`6e4471ad`, 2025-10-28) removed `contain-paint` to fix a node sizing issue — likely because `contain-paint` clips content to the element's padding box, which would clip selection overlays and footer tabs that extend beyond the node boundary via negative insets. Removing `contain-paint` while keeping `contain-layout contain-style` on the outer container broke paint isolation between nodes. Without paint containment, the browser's compositor no longer treated each node as an isolated painting unit, allowing text from lower z-index nodes to visually bleed through higher z-index nodes. ## Fix 1. **Move containment inward**: `contain-layout contain-style` is moved from the outer container to the inner wrapper (`node-inner-wrapper`). This preserves layout/style containment performance benefits while keeping them scoped to the node body — away from the stacking context boundary between sibling nodes. 2. **Explicit isolation**: `isolation: isolate` is added to the outer container. While `transform` + `z-index` already create a stacking context, `isolation: isolate` provides an unambiguous signal to the browser's compositor to treat each node as an isolated compositing unit — replacing the paint isolation role that `contain-paint` previously served, without clipping overlays. ## Red-Green Verification | Commit | Status | Purpose | |--------|--------|---------| | [`feb8555`](https://github.com/Comfy-Org/ComfyUI_frontend/commit/feb855501) `test:` | 🔴 Red (verified locally) | Test asserts `isolate` on outer container and `contain-layout contain-style` on inner wrapper only — fails against current main | | [`c47f89e`](https://github.com/Comfy-Org/ComfyUI_frontend/commit/c47f89ed2) `fix:` | 🟢 Green (CI: Tests Unit passing) | Moves containment to inner wrapper, adds `isolation: isolate` — test passes | **Local red verification:** ``` AssertionError: expected [ 'group/node', 'lg-node', …(9) ] to include 'isolate' ❯ src/renderer/extensions/vueNodes/components/LGraphNode.test.ts:264:26 ``` ## Test Plan - [x] CI red on test-only commit (verified locally — test fails without fix) - [x] CI green on fix commit (CI: Tests Unit passes) - [ ] Place a String Literal node with long text on the canvas - [ ] Place a Load Image node (with an image loaded) overlapping the String Literal - [ ] Verify text from the String Literal does NOT bleed through the Load Image node - [ ] Verify node selection outlines, error borders, and footer tabs render correctly --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Co-authored-by: github-actions <github-actions@github.com> Co-authored-by: Alexander Brown <drjkl@comfy.org>
Release Schedule
The project follows a structured release process for each minor version, consisting of three distinct phases:
-
Development Phase - 2 weeks
- Active development of new features
- Code changes merged to the development branch
-
Feature Freeze - 2 weeks
- No new features accepted
- Only bug fixes are cherry-picked to the release branch
- Testing and stabilization of the codebase
-
Publication
- Release is published at the end of the freeze period
- Version is finalized and made available to all users
Nightly Releases
Nightly releases are published daily at https://github.com/Comfy-Org/ComfyUI_frontend/releases.
To use the latest nightly release, add the following command line argument to your ComfyUI launch script:
--front-end-version Comfy-Org/ComfyUI_frontend@latest
Overlapping Release Cycles
The development of successive minor versions overlaps. For example, while version 1.1 is in feature freeze, development for version 1.2 begins simultaneously. Each feature has approximately 4 weeks from merge to ComfyUI stable release (2 weeks on main, 2 weeks frozen on RC).
Example Release Cycle
| Week | Date Range | Version 1.1 | Version 1.2 | Version 1.3 | Patch Releases |
|---|---|---|---|---|---|
| 1-2 | Mar 1-14 | Development | - | - | - |
| 3-4 | Mar 15-28 | Feature Freeze | Development | - | 1.1.0 through 1.1.13 (daily) |

Release Summary
Major features
v1.5: Native translation (i18n)
ComfyUI now includes built-in translation support, replacing the need for third-party translation extensions. Select your language
