ADDITIONAL INFORMATION

Comment 1 Halla Rempt 2018-10-06 18:24:54 UTC

I'm sorry, I cannot reproduce this either.

Comment 2 Jaime Torres 2018-10-09 07:20:52 UTC

In the nighly build git 5b8b881 I can't reproduce this any more.

Comment 3 Jaime Torres 2018-10-09 08:00:14 UTC

Sorry for the noise. Can't reproduce with 3508px * 4960px * 300dpi 8 bit colour document.
Can't reproduce with a 1*1*300dpi 32 bit colour document.
But I can reproduce it with 3508px * 4960px * 300dpi 32 bit colour document only with Use texture buffer enabled.
This is a faster way of getting the same result as in #399276

Comment 4 Halla Rempt 2019-05-09 10:19:21 UTC

On my intel system, I simply cannot reproduce this. We did fix one issue with 32 bit/channel images, but that was a crash on creation. I think you're running out of resources here.

Comment 5 Jaime Torres 2019-05-09 17:27:15 UTC

Can't reproducem either because the forced environment patches or because today nightly release has it fixed.
