Summary

• Move --enable-unsafe-swiftshader into chromiumSwitches so the Electron loader applies it too, and drop the per-launcher copies in the Chromium and Bidi launchers.
• Without it, WebGL is blocklisted in Electron on machines without a GPU, which fails SS-095 should capture webgl canvas after its drawing buffer is resized in the Electron page tests: https://github.com/microsoft/playwright/actions/runs/39828708914/job/119998797057
• Supersedes test(electron): enable software WebGL in page tests #43596 per the review comment there.

🟢 The completed CI failures are pre-existing

Hi, I'm the Playwright bot. I checked the PR changes, job logs, and refreshed CI test history.

Details

The failure in the latest merged report, and all failures in the other completed jobs, have matching failures outside this PR. Moving --enable-unsafe-swiftshader preserves the normal Chromium/Edge launch flags. Firefox BiDi and WebKit do not use the changed launch code.

Pre-existing flake — Chromium video/trace

[chromium-library] › library/video.spec.ts:762 › screencast › VI-030 should work with video+trace fails because the trace contains no screencast-frame, so reading frame.file throws. The same test, project, Ubuntu bot, and error fail all four attempts on main at the PR's base, b4695e3, in run 40040852369. Outside this PR, this bot's final verdict is failed in 12 of 110 executions and passed in 98.

Pre-existing flakes — Windows Edge

All three tests time out after 30 seconds. Each has independent evidence on the same project and browser/platform:

Test (chromium-library)	Evidence outside this PR
library/chromium/connect-over-cdp.spec.ts:333 — CD-011 should connect to existing service workers	Timed out twice, then passed on main at 7d001dc in run 40035382192, on Edge.
library/defaultbrowsercontext-2.spec.ts:146 — DC-027 should goto about:blank on relaunched persistent context	Timed out twice, then passed on #43611 at cd4fe42 in run 40035552105, on Edge Dev.
library/downloads-path.spec.ts:105 — downloads path › DO-044 should delete downloads when persistent context closes	Timed out all four attempts on main at b4695e3 in run 40040852391, on Edge Dev.

Pre-existing flakes — Windows WebKit tracing

[webkit-library] › library/tracing.spec.ts:565 › TR-023 should produce screencast frames fit/scale time out while waiting for animation frames in rafraf. Both variants also time out on the same Windows bot on main: fit at b80bcb5 in run 40033879070, and scale at 7d001dc in run 40035382192. Both also have passing executions outside this PR.

Pre-existing failures — Firefox Nightly BiDi

All 12 failures have matching failures in their respective moz-firefox-nightly-library / moz-firefox-nightly-page projects on main at 20a2087, in scheduled run 39880181433:

File	Tests
library/browsercontext-service-worker-policy.spec.ts	WO-028, literal and cache-only offline navigation
library/emulation-coop.spec.ts	EM-025, EM-026, EM-027, preserving emulation options
library/firefox/launcher.spec.ts	FF-004, fractional device scale factor
library/har.spec.ts	HA-113, binary content encoded as base64
page/page-drag.spec.ts	DD-028, default drop effect
page/page-filechooser.spec.ts	FC-026, user activation
page/page-keyboard.spec.ts	KB-023, KB-024, numpad keys
page/page-set-input-files.spec.ts	IF-003, folder upload via label

These are existing Firefox BiDi failures, not evidence of a regression from the Chromium flag change.

Scope: completed jobs as of 2026-10-24 00:19 UTC, for PR head 9e51c85. Some tests 2 jobs were still running; this verdict does not cover their eventual results.

🟡 Most CI failures are pre-existing; two remain uncertain

Hi, I'm the Playwright bot. I checked the latest CI report, the PR changes, and refreshed CI test history.

Details

For PR head 9e51c85, the latest merged report has 48 failed tests and one worker teardown error. Including the earlier Chromium and Firefox BiDi jobs, 59 of 61 failed tests have matching failures or failed retries outside this PR, with the same project, file, title, and browser/platform bot. I found no confirmed PR-caused failure, but cannot call the remaining two flakes.

The change preserves the normal desktop Chromium/Edge switches, apart from their order. It adds the SwiftShader flag to Electron, Android, and non-macOS Chromium BiDi. Firefox launch code is unchanged; however, Firefox recorder tests also start a Chromium UI, so their browser label alone does not exclude a connection.

Uncertain — two Windows Firefox recorder tests

Both fail all four attempts in the Windows Firefox job:

Test (firefox-library)	Failure
library/inspector/pause.spec.ts:169 — pause › IN-011 should disable timeout on paused actions	Context teardown times out initially; retries fail because page.click('button', { timeout: 1000 }) times out while stepping through the paused action.
library/selector-generator.spec.ts:51 — selector generator › GN-029 should prefer role=button over inner span	page.setContent times out initially; all retries time out in page.$eval.

In the refreshed history, each test passed all 312 executions outside this PR, including 15 on this Windows bot, without a failed retry. The surrounding Firefox failures suggest an existing browser/runner problem, but that is not proof for these two tests. Their recorder UI uses the changed Chromium launcher, although its effective switches are preserved. A comparison of base b4695e3 and head 9e51c85 on the same Windows image is needed to settle this.

Pre-existing failures / flakes

Group	Evidence outside this PR
Windows Firefox: the other 40 failed tests	Exact matches on the same Windows bot: 37 failed/flaked on main at ca7ca36 in run 39721827934. The remaining three, GN-028 (selector generation), WM-007 (tool timeout), and [firefox-page] EH-011 (detached-node click), failed/flaked on main at b80bcb5 in run 40033879070.
Firefox fatal error: worker teardown	The blob report identifies a 30-second worker teardown timeout after library/proxy.spec.ts:255 › PR-010 should exclude patterns. The same worker-teardown error also occurs on the PR's base, b4695e3, in run 40040852391, there after permissions tests. PR-010 itself also has failures outside this PR. This supports existing Firefox shutdown trouble, not a new SwiftShader failure.
Chromium video/trace — library/video.spec.ts:762 › screencast › VI-030 should work with video+trace	The same Ubuntu bot fails all four attempts with the same Cannot read properties of undefined (reading 'file') error on base b4695e3 in run 40040852369.
Windows Edge Dev — library/defaultbrowsercontext-2.spec.ts:146 › DC-027	The same test times out twice, then passes on the same Edge Dev bot on #43611, cd4fe42, in run 40035552105.
Windows Edge Dev — library/downloads-path.spec.ts:105 › downloads path › DO-044	The same test times out all four attempts on the same bot on base b4695e3 in run 40040852391.
Windows Edge — library/chromium/connect-over-cdp.spec.ts:333 › CD-011	The same test times out twice, then passes on the same Edge bot on main at 7d001dc in run 40035382192.
Windows WebKit tracing — library/tracing.spec.ts:565 › TR-023 should produce screencast frames fit/scale	Both variants time out all four attempts on the same Windows bot on main at b80bcb5 in run 40033879070. WebKit does not use the changed launcher.
Android page error — page/page-event-pageerror.spec.ts:20 › ER-001 should fire	The same android-page test fails with the same Uncaught Error: Fancy error! versus Error: Fancy error! mismatch on #43611, cd4fe42, in run 40035550970. Android receives the new flag, but this assertion failure already exists without it.
Firefox Nightly BiDi: 12 failures	All 12 exact test identities also fail in their respective moz-firefox-nightly-library / moz-firefox-nightly-page projects on base b4695e3 in scheduled run 40046453583: WO-028 (both offline-navigation variants), EM-025/026/027, FF-004, HA-113, DD-028, FC-026, KB-023/024, and IF-003. These are existing failures, not necessarily intermittent flakes; Firefox BiDi does not use the changed Chromium switches.
