From 25e3e800df8e5caf18d7e846a0cd36df4f5834f9 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Tue, 10 Nov 2026 16:42:39 -0500 Subject: wiki: 2026-11-10 afternoon refresh - first real GPU readback; direct-GL/window walls Refresh STATE-CURRENT, the Main Page and the status/frontier pages: the DDX 3D replay executes and a guest pbuffer glClear+glReadPixels returns a red pixel (ff0000ff); the RM write-lock holder (Xorg in the DDX scrub wait) is fixed in df6e71bb. The direct-GL client channel still emits only setup/notify kicks (ops_runs=0), a window draw wedges X, and X startup/RM stability plus the DDX 4 GB sysmem allocation remain.
