Steps of reproduction

  1. Start picom using picom --experimental-backends -b.
  2. All of the opacity rules are not applied.
  3. The windows mentioned in those rules can be made transparent using picom-trans -s -o 85.

Expected behavior

My opacity rules should work as expected. The window class names are accurate and do match when I check them with xprop.

Current Behavior

The opacity rules are not being enforced. Out of my list, only the rule for polybar is working. Rest all are not being applied.

Other details

I've tried using my system on integrated graphics and the same issue still occurs.

Does it have anything to do with _NET_WM_WINDOW_OPACITY and the fact that picom-trans specifically targets that property? Moreover, if I do picom-trans -g and pick my terminal st (which handles opacity values from .Xresources), the output shows the opacity as 100 which is not expected since the window already had blur on.

Any help is appreciated. It has been a few weeks since this suddenly stopped working.

Can you please give a minimal config for reproducing this behaviour?

For e.g.-

focus-exclude = [ "class_g = 'Cairo-clock'" ];
opacity-rule = [
    "85:class_g = 'Code'",
    "10:class_g = 'spotify'",
    "88:class_g = 'discord'",
    "85:class_g = 'obsidian'",
    "85:class_g = 'Polybar'",
    # "0:_NET_WM_STATE@:32a *= '_NET_WM_STATE_HIDDEN'"
]
backend = "glx";
mark-wmwin-focused = true;
mark-ovredir-focused = true;
detect-client-opacity = true;

Try using the above configuration. Does it work? (i.e. are opacity-rule working?)

tryone144 commented 3 years ago

Just out of curiosity:

The individual _NET_WM_WINDOW_OPACITY property has higher precedence than the opacity-rule.

Moreover, if I do picom-trans -g and pick my terminal st (which handles opacity values from .Xresources), the output shows the opacity as 100 which is not expected since the window already had blur on.

Unless you have explicitly specified the windows opacity via the _NET_WM_WINDOW_OPACITY property, this is the expected output. picom-trans does not reflect whether a window uses the alpha channel for its background to become (partially) transparent, which I suspect you patched your version of st to do.

It seems that I have been using the same config as the one you provided. So the issue still persists.

PrayagS commented 3 years ago

Thanks @tryone144 for your response. I appreciate it.

Just out of curiosity:

  • Did you have another compositor running before?

No, picom is the only compositor that's been running.

  • Does any of the affected windows have the _NET_WM_WINDOW_OPACITY atom set?

Using xprop, I noticed that all of those windows have the following property with the same value,

_NET_WM_WINDOW_OPACITY(CARDINAL) = 4294967295

Even my terminal (st) has the same property. And in case of st, I am not facing any issues.

Unless you have explicitly specified the windows opacity via the _NET_WM_WINDOW_OPACITY property, this is the expected output. picom-trans does not reflect whether a window uses the alpha channel for its background to become (partially) transparent, which I suspect you patched your version of st to do.

Ah, I see. Thanks for the explanation.

tryone144 commented 3 years ago

Using xprop, I noticed that all of those windows have the following property with the same value,

_NET_WM_WINDOW_OPACITY(CARDINAL) = 4294967295

That is interesting. picom does not change that property anymore since 79fc36b3e30989fd638aa0531588e02b564a906c as that did cause its own set of issues (see #134). So if your windows have that property set, then there must be some other piece of software responsible for it.

My personal i3 setup does NOT set the _NET_WM_WINDOW_OPACITY property for any window (tested explicitly with discord and code-oss). However, I'm a bit suspicious about Code, spotify, discord, and obsidian all being electron apps. Wild guess, but are you running a patched electron engine? IIRC there was a project that intended to provide true alpha-transparency through themes in electron apps. Something like that could actually be the root-cause of this issue.

Even my terminal (st) has the same property. And in case of st, I am not facing any issues.

Do you mean st has _NET_WM_WINDOW_OPACITY(CARDINAL) = 4294967295 set as well? This value equals 100% opacity of the window — it can still have alpha-transparency in its texture. Do opacity-rules for st work? (I don't expect them to.)

Edit: You may want to check if the rules start working after removing the offending property with xprop -remove _NET_WM_WINDOW_OPACITY.

IIRC there was a project that intended to provide true alpha-transparency through themes in electron apps. Something like that could actually be the root-cause of this issue.

I tried setting a rule for other windows as well and it's not working. The reason that it is working with st has been made pretty clear by you. Is there any way I can see which piece of software is setting that property?

Edit: You may want to check if the rules start working after removing the offending property with xprop -remove _NET_WM_WINDOW_OPACITY.

Yep, I tried this and it does work. So now I just need to find who's messing with the window properties. Thanks for all your help till now. Please let me know if you have any more leads. And yeah I'm not sure but since this issue isn't being caused by picom, feel free to close it.

PrayagS commented 3 years ago

Update.

As @tryone144 correctly pointed out, some other piece of software is messing with the window properties. I really wish I had an answer but during troubleshooting (I noticed dunst had transparency enabled in its config. Maybe it was setting the property.) and after a restart, all my rules were working fine.

Thanks again everyone for your help, especially @tryone144. I started using your compton fork way back when and I'm glad you ported those blur techniques to picom as well.

This solved my problem. My issue was that newly opened applications (like firefox or alacritty) windows didn't receive the specified opacity/transperency (defined in active-opacity && incative-opacity). The transperency only worked when I had the applications opened up and restarted i3 and therefore picom too.

After I added my applications, according to the pattern, to the opacity-rule list , the opacity also worked on newly opened application windows. Thank you very much.
