PSD thumbnail is pixelated. Possible improve quality?

[cadu]

Hi,

I'd appreciate help. Using XnViewMP 0.87_3.
As showed in the snapshot below, PSD thumbnail is pixelated in comparison to JPG. Thumbnails from JPG a high quality, and I'd like better quality for PSD too. Is it possible? How to?

Thanks,
Carlos

perhaps the embedded thumbnail is small, do you have the setting Thumbnail>Create from original if...

Thanks for reply!
The setting "Thumbnail>Create from original if..." seems that's not working for PSD files.
The only way PSD thumbnail improved was after unchecking "Use embedded thumbnail".
However, this global change affects DNGs thumbnail, which becomes "black" after rebuilding them.
Then to have PSD great thumbs causes DNG thumbs issues (and vice-versa)
I recorded my screen showing the issue in details: https://goo.gl/UZTXVg
Any workaround to have both PSD and DNG with great thumbnail quality?
