…window + first-paint gate (#27) From Beeper 4.3.123 the renderer stalls on Chromium's default GL fallback under Xvfb: the window is created but never mapped, so the login screen never renders and first-run noVNC login is impossible. The API still comes up, so the HEALTHCHECK and the MCP guard matrix passed and the weekly rebuild shipped it. - entrypoint.sh: launch beepertexts with --use-angle=swiftshader - scripts/first-paint-check.sh + vnc-paint-probe.py: boot the image on a fresh profile, read the framebuffer over VNC from the host, fail on a blank screen - wire the gate into mcp-test.yml and release.yml verify - docs: CLAUDE.md, PRD, CHANGELOG Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01U1PKBQDukuTNc4Eak9icLz
…ed RFB handshake Follow-up to the #27 fix from the self-review: - first-paint-check.sh: pass needs two consecutive samples >= 1000 colours (a mid-paint frame no longer passes); a probe error is reported as such instead of "screen still blank"; unique container name + docker-assigned port so concurrent runs don't collide - scripts/rfb.py: one RFB handshake shared by vnc-auth-probe.py and vnc-paint-probe.py (no behaviour change to the auth probe) - release.yml: verify-arm64 job on the native arm runner runs the first-paint gate; publish and notify-failure wait on it (not yet executed) - stamp 0.9.1: mcp/package.json, CHANGELOG, CLAUDE.md, PRD Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01U1PKBQDukuTNc4Eak9icLz

:latest(Beeper Desktop 4.3.123) the Beeper window is created but never mapped under Xvfb, so the login screen never renders and first-run noVNC login is impossible. The API still comes up, so the HEALTHCHECK and the MCP guard matrix passed and the weekly rebuild published it.Fix
entrypoint.shlaunches Beeper with--use-angle=swiftshader(SwiftShader ships inside the AppImage; no new packages).--disable-gpu/--disable-gpu-compositingdo not help.Gate
scripts/first-paint-check.shboots the image on a fresh profile, reads the framebuffer over VNC from the host, and passes only on two consecutive samples of 1000+ colours (blank = 2, login screen ≈ 11,000).mcp-test.ymlandrelease.ymlverify, plus a newverify-arm64job on the native arm runner that publish waits on.scripts/rfb.py: one RFB handshake shared by both VNC probes.Release
Stamps 0.9.1 (PATCH).

:latest(2 colours) and passes on an image built from this branch pinned to Beeper 4.3.123; also passes on 4.2.923.node --test mcp/server.test.js: 48/48.asset-serve-check: pass.mcp-guard-check.sh,vnc-auth-check.sh(CI runs both here). Theverify-arm64job has never run; it first runs on thev0.9.1tag push.🤖 Generated with Claude Code
