When used together with copyq, imv display all black:
copyq read image/png | imv -
However when I save the output of copyq to local file, then imv would display without problems:
copyq read image/png > a.png
imv a.png
Here is a test file for reproduction: https://github.com/tianze0926/picx-images-hosting/raw/master/20240410/image.70a4blo8r9.png
imv image.70a4blo8r9.png # WORKS
cat image.70a4blo8r9.png | imv - # NOT WORKING
