BTW
Pierre-Eric can you look into this
Shadertoy shader corruption, too? https://www.shadertoy.com/view/Xt3cWS
The "Buffer A" shader doesn't write fragColor when uv.y is < 0.1 or > 0.9.
So the content is undefined and may be black on some platform or random.
radeonsi is correct here, but we might want to replace undef values with 0x0 to get a default value instead of random.
Cool to have you around for bug hunting...;-)
Any hints where I shoud change 'undef values with 0x0' for testing?
And sorry that I 'hijacked' this thread - should I open a new ticket?
