The previous issue was locked, so i opened a new one.

[allusive-dev]

@apprehensions It has become clear to me at least that this is an issue with your system. I have tested under the same circumstances and not come across this issue, as well nobody else seems to have come across this issue.

Best I can suggest is you review your system and possibly try testing the issue on another system.

Apologies for the other issue, I thought you would still have access after I locked it.

[apprehensions]

While i still don't know how to debug very well, I still firmly believe the fault was due to a signficant code change done in this project. Picom vanilla runs perfectly fine.

[apprehensions]

Is there another stable Picom fork with animations i can use as a point of reference?

[allusive-dev]

Is there another stable Picom fork with animations i can use as a point of reference?

https://github.com/pijulius/picom

[apprehensions]

That fork you linked works.

[apprehensions]

I'm not sure what exactly happened in code of project, but theres thousands of code changes which are purely style... This makes it so much damn harder to track down the original issue

[apprehensions]

https://github.com/fdev31/picom also works

[allusive-dev]

Stumps me how you got both yshui and pijulius to work but not mine

What makes less sense is how this is only happening for you.

[apprehensions]

Are you on the Picom discord? we can discuss further there

[allusive-dev]

I was not aware picom had it's own discord server.

[allusive-dev]

@apprehensions Can you send the link, I cannot find it.

[allusive-dev]

I'm in #development

[allusive-dev]

Resolved. Building with meson setup -Dregex=true build causes the issue. To resolve use this command when building.

meson setup --buildtype=release . build

[apprehensions]

Yep.
