Comment (by alexpigment):

 This doesn't appear to be addressed on my end. I've tested the latest
 Zeranoe build, but I also compiled a nightly Win32 build with the relevant
 patch applied. See "stairstepping.png" attachment.

 Did either dpavlekovic or oromit test the reproduction steps to make sure
 the fix worked in that scenario?
