Bug ID: 109207
Summary: `override_redirect` windows are not visible on amdgpu
Product: xorg
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/AMDgpu

`InputOutput` windows with the `override_redirect` flag set in the
`XSetWindowAttributes` structure, alongside the `CWOverrideRedirect` mask set
when calling `XCreateWindow` should display a window after mapping (parent to
root window).
This is not the case on amdgpu, the window receives a single
`VisibilityFullyObscured` event and is never seen. The `map_state` attribute is
always `IsViewable`, raising the window has no effect, focusing the window
grabs input focus but does not show the window.
All other drivers behave accordingly here by providing a visible window. This
flag is essential for allowing certain window behavior independent of an active
window manager, including an application I maintain.
Affected system info:
$ pacman -Ss xorg-server
extra/xorg-server 1.20.3-1 (xorg) [installed]
Xorg X server
...
$ pacman -Ss amdgpu
extra/xf86-video-amdgpu 18.1.0-1 (xorg-drivers) [installed]
X.org amdgpu video driver
$ glxinfo | grep "renderer string"
OpenGL renderer string: Radeon RX 560 Series (POLARIS11, DRM 3.27.0,
4.19.2-arch1-1-ARCH, LLVM 7.0.0)
Tested with nouveau, nvidia, intel, llvmpipe to assert that the behavior is
consistent. Feel free to ask for additional details.
