System Information
Operating system: Linux-4.15.0-50-generic-x86_64-with-debian-stretch-sid 64 Bits
Graphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 384.130

Blender Version
Broken: version: 2.80 (sub 72), branch: blender2.7, commit date: 2019-05-29 18:17, hash: fee600f479

Short description of error
Blender fails to work correctly with narrow (1 px or 2 px) and long (>256 px) images. Image Editor fails to show these images correctly, which is demonstrated by python script in the attached blend file. Also png images generated with GIMP behave similarly when loaded into Image Editor.

Exact steps for others to reproduce the error

blender --factory-startup
load attached blend file
run script
in Image Editor view generated images. Images that are OK show up white as expected. Images that are NOT OK show up as transparent.

Unable to reproduce. Could be that this used to be an issues, but has been fixed when overhauling the image editor drawing. @lichtwerk were you able to reproduce this one?
