bug transparancy

[nda-cunh]

it is impossible to assign alpha values to gtk-layer-shell widgets. example:

create a window with rgba(250,0,0,1); will create a completely opaque window however if I put rgba(250,0,0,0); it will create a completely transparent window! This shows that layershell is compatible with transparency and that it is probably a bug.

There is also the fact that my compositor can't blur the transparent widget created by layershell. (But I think it's the same problem)

I just set the windows background to rgba(0, 0, 0, 0,5) through CSS

[nda-cunh]

Ah yes... but normally the css is from 0 to 255 not 0.5 on widgets out of layershell but it doesn't matter, it works!

so there is still the problem with the fact that the composer doesn't put blur on transparent widgets when they are on layer shell

with layer shell

without layershell

Ah yes... but normally the css is from 0 to 255 not 0.5 on widgets out of layershell but it doesn't matter, it works!

The first 3 are R,G,B which can be from 0 to 255 while the last one stands for Alpha which goes from 0 to 1

okay I see so it's GtK who made a mistake so for the CSS I'll take it.

for the blur I have to ask wayfire or it comes from layershell?

[ErikReider]

I'm not familiar with the layer shell code so I don't know. Hopefully somebody else does :)

The blur comes from Wayfire. You probably have not set up all surfaces to be blurred, see https://github.com/WayfireWM/wayfire/issues/1399 for a similar issue and a solution which should work for you.
