Shadows don't work properly with rounded corners

[ItsDrike]

Environment

OS: Arch Linux (5.14.16-arch1-1) Picom version: vgit-a8445

Current Behavior

When I enable both shadows and the rounded corners, while the rounded corners do work just fine, there is a non-rounded shadow that over-reaches behind the corners which doesn't look very good.

Expected behavior

Shadows should respect the rounded borders and shouldn't be drawn outside of it.

I faced this issue too, Any fixes?

[Atavixion]

found a fix on ibhagwan's fork but dont know how to merge it with jonaburg's fork

[Arian8j2]

@Atavixion Thanks for mentioning it, I forked jonaburgs one and applied changes by hand, Now every thing works fine! You can find my fork at here. Thanks a lot to @s0nny7 too for his amazing commit.

[Atavixion]

@Arian8j2 it still has the same behaviour for me running it with experimental-backends = true, and there are no shadows running it with experimental-backends = false. On ibhagwan's fork, it worked fine without experimental-backends. Hope this helps in some way :0

[Arian8j2]

@Atavixion can you post your config file

[Atavixion]

ok i somehow fixed it by rebuilding it, everything seems to work now :D

[Arian8j2]

Yeah i was just posting a comment about make sure that you are using the new one tho, Happy to hear it got fixed.

[Atavixion]

thanks :3, are u going to merge your fork with jonaburg's ?

[Arian8j2]

I don't think so, cause its actually @s0nny7 work and I just merged it with @Jonaburg fork, And it seems like @Jonaburg isn't updating his fork anymore, It passed about 1 years from his last commit.

[Atavixion]

ok, can i then put ur fork on the aur?

[Arian8j2]

Yeah, that sounds cool, I really appreciate it.

[Atavixion]

ok, here's the AUR Package

[Arian8j2]

Great !

[Arian8j2]

For anybody that is looking for quick fix, There is a package in AUR called picom-jonaburg-fix (thanks to @Atavixion for maintaining), Just install and use it instead of original fork.

This worked perfectly for me, thank you for this and many thanks to @Atavixion

I wish this would be pushed to the main picom fork

This works well but the shadow don't always show for me. Sometimes when I run the picom command/start with bspwm config file the shadows get shown but other times they just don't appear. Any solution?

I run bspwm as well and have had no problems so far. Maybe it is your picom config? Another person running Herbstluftwm also had this issue. Post your config and i can try to help my best :)

My picom config file (sorry its kind of messy): https://pastebin.com/rwLJB6vq

I'm currently running picom with the command: picom --config $HOME/.config/picom.conf --experimental-backends

[Atavixion]

Everything looks fine to me, except I have detect-client-opacity = true; set to false. Also, you don't have wintypes but im not sure if that changes anything. I doubt this will do anything, but copy the default config to .config/picom/picom.conf and turn on shadows from there. Sorry if none of this helps -w-"

Could you by any chance send your config file? Perhaps it'll work for me too?
