Description
The following Shadertoy demo:
https://www.shadertoy.com/view/Xt3cWS
renders garbage in the top and bottom strips of the target surface, which appears to be uninitialized VRAM being copied to the display surface.
It does not appear to matter which WebGL capable browser I use to run the demo, they all replicate the issue on my RX480.
I cannot get apitrace to run on Firefox without that particular page crashing on load, and I cannot get RenderDoc to attach to the tab's process and actually capture anything.
