Steps of reproduction

Enable fly-in animaiton for open window

Expected behavior

No left-overs on my screens

Current Behavior

Small artifacts from what looks like previous buffers, all over the screen. Can be cleared by moving another window over them.

dccsillag commented 3 years ago

I see. This looks like the pretty much the same artefacts as what was reported in https://github.com/dccsillag/picom/issues/18; however, for you, that happens on both the xrender and the glx backend.

Right now I have no idea why this happens. But it's good to know that it's not really particular to xrender, it's just that, for some reason, my glx is different and probably redraws everything all the time, even when it's not needed.

Icelk commented 3 years ago

I use Dunst, which moves to the screen I'm focused on. With this fork, it slides smoothly. When entering the other screen, it turns completely black. This does not happen with regular picom. It seems to be related.

I tried turning damage off. It did not help. I also fiddled around with several other settings, none resolved it.

dccsillag commented 3 years ago

Oh, interesting! This seems really close to what happens in https://github.com/dccsillag/picom/issues/18; it's good to see another person with a similar enough problem.

Don't know how related it is to this particular issue, but it's at least probably in the same part of the code (the changes to backend code).

I think I won't have time today, but I'll make a patch which reverts backend code to how regular picom does it; then, we can see if these issues still happen there (and thus start to isolate the problem).

Icelk commented 3 years ago

Thanks a lot. Just tell me if you need any more info 👍

dccsillag commented 3 years ago

This was/is probably fixed in https://github.com/dccsillag/picom/pull/22. Can you confirm?

Icelk commented 3 years ago

@dccsillag Will try when I come home to my multihead setup. Btw, great work on implementing this! It feels soo good 😃

Icelk commented 3 years ago

@dccsillag I now tried this, and the artefacts don't appear, but Dunst still appears black sometimes.

Here is a video showcasing the issue. This is using the latest commit in @pijulius fork.

dccsillag commented 3 years ago

Do you think this is an instance of https://github.com/dccsillag/picom/issues/13? In fact, you can now check, since @pijulius apparently was able to fix it just a bit ago (but after this last message of yours)!

Icelk commented 3 years ago

Will check when I come home today. The issues in #19 seems to be amplified with the latest changes, while testing on my laptop.

Icelk commented 3 years ago

The issue is resolved with @pijulius latest commit. Should we leave this open till his code is merged?

dccsillag commented 3 years ago

Great!

Yeah, we'll close this only when the code is merged.

Icelk commented 2 years ago

This is fixed now. Thanks!
