I reverted to 23.3 and then stepped through the changes. Frankly, do not see why i need to make changes with prior version - the multi-window/crashing has gone but the images on export are messed up - all color are messed up/white balance gone. I export in .png with Transparency, 8bit, convert to sRGB and Embed Color Profile selected. When i deselect 8 bit - the color is right but the file is giant - i am need a constant 3Kx3K pixel size and use 8-bit selector to keep file size smaller. So - not sure what i do now - should i go back to 23.2.2?
I reverted to 23.3 - does not show the "0" as you described. I noted last night that the whole white balance/color issue seemed to be intermittant - on small file sizes (with the overall canvas being ~3K by 3K), smart objects are a bit smaller - the issue seemed to occur when exporting full size. For 5K x 5K canvas it occurs at full size export and 3kx3k export but when i got to 1k x 1k it would not - meaning i could leave 8 bit unselected. otherwise - previously i could downshift file size just by selectng 8 bit - now it no longer works unless i make image much smaller
