i915->amdgpu pipe renders garbled images

Running waypipe-0.8.3 on sway-1.7 (x86_64). Client application runs on i915 and sway as a wayland server runs on amdgpu.

I get the following garbled images:

• 
• 

Ran the test as waypipe ssh i7 es2gears_wayland. Most GL-accelerated applications have a similar damage (alacritty, flare).

Kernel 5.19.11 on both machines. mesa-22.1.7.

Client GPU (rendering, without display):

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
        Subsystem: Gigabyte Technology Co., Ltd Device d000
        Kernel driver in use: i915
        Kernel modules: i915

Wayland server GPU (with display):

09:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Baffin HDMI/DP Audio [Radeon RX 550 640SP / RX 560/560X]
        Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Baffin HDMI/DP Audio [Radeon RX 550 640SP / RX 560/560X]
        Kernel driver in use: snd_hda_intel
        Kernel modules: snd_hda_intel

It looks as it some stride is off.
