Blender 2.8 freezes when save buffer is enabled and the rendering is cancelled
Closed, ResolvedPublic


System Information
Operating system: Ubuntu 18.04.1
Graphics card: RX 480

Blender Version
Broken: blender-2.80-141c6073ca39
Worked: blender 2.79.6

Short description of error
If you enable the save buffer option in cycles, in 2.8, the render result is empty while rendering, and if you cancel while rendering it freezes blender, if you let the render to completion it doesn't crash.

ps: I made an empty task, then edited this, sorry

Seems to hang in IMB_exrtile_write_channels
specifically: out.writeTile(partx / data->tilex, party / data->tiley, level); never returns nor throws an error apparently

Not sure if this is related, but doesnt seem to hang if multiple of tilesize fit nicely into image size:
e.g. Tilesize of 256x256 and rendering 2048x2048 doesnt seem to have this problem.
[totally unsure how this has an effect though]

@Brecht Van Lommel (brecht): is this something for you?
