Blender 2.80
Hi all, I'm not sure if this has been reported - but when I render an Open EXR file in Blender 2.8 - the file is unreadable in both Vegas Pro 16 and Hitfilm (latest version). I had been using Blender 2.8 - version from January off the top of my head, and this rendered out readable Open EXR files. Since Feb when I tried a later version - the EXR file was not readable by both programs already mentioned. What's worse is, when I downloaded and used the release client of 2.8 - the version I was using to render out the EXR file format no longer worked - I could not press back on the mouse.
Now even stranger is, when I switched to Evee - the EXR files are readable in both mentioned programs.
Finally I should mention that I am trying to open older Blender files and Blendswap files in the realease client of 2..8
Hopefully someone can fix this problem. 2.79 is just far too slow. In fact it is useless after using 2.8 for some months now, and in regards to render time.
Thanks

I am getting the same message as in #66515 when I open the EXR up in Krita:
@JuanRomero : you were also experiencing problems loading EXRs in photoshop, right?
@Sergey, @brecht: has there been changes on how we treat alpha? or have we upgraded OpenEXR (Jannuary/February)?

Please provide concise steps to reproduce the issue. Based on the current description I have to guess what I have to do to reproduce it, and I'll probably guess wrong.
@Neb55 : I have updated the task description, could you please check if
is still unreadable in other apps for you?
For me, I am still getting
in Krita, will have to check if this is in fact an issue or something to be expected...
For premultiplied alpha images like EXR, zero alpha and non-zero color is entirely valid, it's how you can represent emission without opacity. Krita like most painting apps uses a different convention, so there will be some data loss in such conversions, and Krita shows a warning for that.
I think it's unlikely that this would make the file unreadable in any application, so it's probably unrelated to this report.
