screen blurs when taking shot

[TheContortion1st]

Hi,

when I take a selective screenshot (-s) the screen blurs and so the screenshot is blurred as well.

When I take a normal screenshot (w/o any option) it is crystal clear and with correct resolution. Any idea, what could cause this?

I'm using a Laptop with shut lid (1920x1080) working at a 27" monitor (2560x1440), configured via arand/xrandr in i3, if that's of any relevance.

exec_always --no-startup-id xrandr --output eDP-1 --off --output DP-1-2 --primary --mode 2560x1440 --pos 1920x0 --rotate normal --output HDMI-3 --off --output HDMI-2 --off --output HDMI-1 --off --output DP-1-1 --off --output DP-1-3 --off --output DP-2 --off --output DP-1 --off

I found a solution (workaround?). With the -o option, to not use hardware acceleration, maim does not blur the screen and the shots are crystal clear. It's quite strange though, that the full screen default maim screenshot is normal as well and only the selective option blurs it.

Same problem here with i3

Disabling blur in compton is another workaround.

Yeah, I'm having this issue as well (i3 + compton). Only happened when I turned blur on with compton and maim -o fixes the issue.

Having the same issue running i3 + compton on Manjaro, and i can confirm that using the -o flag on my system does in fact remove the blurring.

If i had to guess, i think i3 is somehow acting as if main -s were a window and as such blurs the background.

This happens because of the compositor's blur effect. If you're using compton, you can add an exclusion for slop in your config without disabling hardware acceleration:

blur-background-exclude = [
    "class_g = 'slop'"
];

Similar/related issue, not sure if I should submit a new one. I just switched to picom-tryone, using a lightly modified default/sample config until I dive further into it. Whenever I go into selection mode -s, all of my displays dim a considerable amount, which is captured in the screenshot.

I've just added "10:class_g = 'slop'", within opacity-rule = [ as a workaround, but this still dims the images slightly. I can set it to 0 opacity, but then the selection box is invisible. I'd love to know how to make slop/maim fully transparent again with the selection box still visible.

Tangentally, if anyone knows how to make picom's blur effect only happen outside of the selection box, let me know.

I was able to solve the dimming issue. Turns out it's not related to opacity, it's related to shadows, so add an exclusion to shadows for slop:

shadow-exclude = [
  "class_g *?= 'slop'"
];

@jeanlucthumm Thank you, that fixed dimming with picom for me!

should this issue be closed now?

i have same issue with xfce4-screenshooter, tried adding it to blur exclusions but still blurring the selective screenshot overlay. Anyone knows the proper exclusion name for xfce4-screenshooter ?

I have no idea about the "select region" widget itself, but maybe you could try something from main screenshooter window information:

        {
            "border": "none",
            "current_border_width": 2,
            "floating": "user_off",
            "geometry": {
               "height": 318,
               "width": 545,
               "x": 410,
               "y": 225
            },
            "marks": [],
            "name": "Screenshot",
            "percent": 0.333333333333333,
            "swallows": [
               {
               "class": "^Xfce4\\-screenshooter$",
               "instance": "^xfce4\\-screenshooter$",
               "title": "^Screenshot$"
               }
            ],
            "type": "con"
        }

blur-background-exclude = [ "window_type = 'dock'", "window_type = 'desktop'", "class_g ?= 'xfce4-screenshooter'", "_GTK_FRAME_EXTENTS@:c" ];

"class_g ?= 'xfce4-screenshooter'", # adding this line fixed issue (picom | manjaro)

I am closing this issue since all workarounds^Wsolutions have been researched. Feel free to open it again if you still have any problems.
