I saw this reported for PhotoAI, but reporting this for Gigapixel just in case.
This is occurring in latest version as of 2025-04-07. Windows 10.
Steps to reproduce:
Open a file called “image.png” in Gigapixel. (I drag and drop the image from my file browser onto Gigapixel.)
Export the image.
Close the image using CTRL-W (which seems to need to be pressed twice now).
Delete image.png in file browser.
Copy in another different image to the same location/path with the exact same filename, image.png.
Open the new image.png in Gigapixel. (Same method, drag and drop, in my workflow.)
Note that it displays the previous image, not the contents of the new image.png.
Only way to clear it is to exit Gigapixel entirely and re-run it.
