I've been using Gimp 2.8 for years and since 2.10, there are some behaviors I really don't get. I searched for hours on the net without finding solutions because I think I miss keywords.
It gave me a lot of headaches for a long time. This behavior is clearly different from previous version of Gimp. I let 2.10 to the side for a long time because it literally destroys a lot of projects and I suspected a bug, but now it's 2.10.30 and it's still there. In 2.8 and before, layer is a layer, that's all, it doesn't disappear or change because of what you did on another layer. I feel like a total dumbass but can't manage to find anyone talk about it.
This behavior did not change with GIMP 2.10, your desktop background or folder background on the other hand certainly did.
It's called "Contrast", and you feel that you don't see it because there is not enough contrast (for your eyes) to see it. Not enough contrast with the background of your software viewer, or the background of your Desktop/Directory-Folder for the thumbnail
Solutions:
- Put that software-viewer in dark mode or take a look at the setting to see if it can shows transparency on a dark background instead of the usual chessboard alike grid.
- Put down the brightness of your screen/monitor. Your screen might be too bright or not calibrated.
- Change the background of your Desktop or background of the folder where you put that .png
Look below I did put your image test in a directory/folder, exported as PNG without the black background, thus it has transparency, I increased the thumbnail view to 400% of this Folder and changed the background of this very-folder and you can even see that the thumbnail made by my OS retains the correct transparency with that slight blur from your image test.
You can even check that your image has retain proper transparency on website like imgur https://imgur.com/a/FlHzrwY (it's your image from the .xcf without the black background)
