In the currently available version of imv on Debian Trixie (4.5.0-1+b4), using a command such as, in the case of a hyprland environment: $ `grim -c -t ppm -o "$(hyprctl monitors | awk '/Monitor/{mon=$2} /focused: yes/{print mon}')" - | imv-wayland -w ForceFullscreen -` Shows correctly pretty much instantly a screenshot of the currently focused monitor. This is useful as you can then run grim again to select just a small portion of the screen while taking as long as you want to do so, useful when your screen is moving around a lot. However, in imv from Debian SID (5.0.1-3), the very same command no longer works and instead shows a black screen, presumably as PPM support was removed(?). It is simple to replace the `-t ppm` part with `-t png -l 0` to achieve almost the same result, however this is in my experience slower and not as fast as PPM. This is a really minor regression and I'm sure there's a good reason for the removal of PPM but in my (very likely unique case), it causes some headaches. I am using Debian Experimental on Linux 6.18-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.18.2-1~exp1 (2025-12-18), however the kernel does not make a difference, manually downgrading imv to 4.5.X does the trick to fix temporarily the problem.
