Subject: [bugreport] Invoking Xorg -retro and using radeon.ko renders root window stipple in colored dots, not B/W standard stipple

Graphic card: RV280 ATI Radeon 9200 Pro (PCI id 1002:5960,subid 148c:2094)
kernel: kernel-5.14.0-427.42.1.el9_4 (Rocky Linux 9.4)
Xorg: xorg-x11-server-Xorg-1.20.11-24.el9
radeon.ko: git master (xf86-video-ati-22.0.0, 888b33c67) to xf86-video-ati-7.10.0


Compiled and installed radeon.ko from https://gitlab.freedesktop.org/xorg/driver/xf86-video-ati.git .

Full power-cycle the machine, and invoking the following for the first time
xinit -- /usr/bin/Xorg -retro 
renders root window stipple in colored dots, not Black/White standard stipple.

Exit the X session, and re-invoking
xinit -- /usr/bin/Xorg -retro 
renders the root stipple correctly.

It looks like something is not initialized when root stipple pattern is rendered.
Application is not affected, works perfectly. Only the root window stipple is the problem.

Uninstalling radeon.ko and using modesetting_drv.so has no problem.

I tried the following versions, and all had the same results.
Since not many people uses Xorg -retro, this seems to be a longstanding bug.
- master 888b33c67
- tag: xf86-video-ati-22.0.0
- tag: xf86-video-ati-19.1.0
- tag: xf86-video-ati-19.0.0
- tag: xf86-video-ati-18.1.0
- tag: xf86-video-ati-18.0.0 (Tue Mar 6 18:15:45 2018 +0100)
- tag: xf86-video-ati-7.10.0 (Fri Sep 8 17:02:59 2017 +0900)
I was not able to rewind further, since the Xorg buildsystem is too recent.
