i have the same problem

[cpiber]

I face the same problem. For me native wayland applications let the background show through, and xwayland (or Electron?) seem to not render properly, where the window is white and the mouse cursor "drags" through.

uh huh intel doesn't like something about the new shaders I am guessing #8943 @polluxcodes

[polluxcodes]

I'll take a look.

[polluxcodes]

Looking at the screenshot, it seems the issue is probably in the Textures.hpp file, since the borders look ok. Can anyone check if the shadows work?

I have shadows enabled like in the default config, anything I should see? I honestly can't see a difference, so maybe no

[polluxcodes]

@cpiber If they are working, you should be able to see them around the borders, but not within them.

[cpiber]

Had to change the color and bump up the range, yes, they're working

[polluxcodes]

@cpiber Do they still work with rounding>0?

[cpiber]

No, setting rounding to a positive number like in the default config creates the above situation. I had shadows enabled like in the default config and encountered that. Tested again to be certain, it happens with and without shadows.

[polluxcodes]

@cpiber Sorry, I meant do the shadows specifically work as I described earlier. I'm trying to see which of the three shaders that I modified are broken.

[cpiber]

My bad, misunderstood. Here is a screenshot of the new shadow. Definitely seems larger than before, and seems to reach into the window.

[polluxcodes]

Actually, the way shadows are rendered, the shadow's shader is probably fine, since it uses the textures shader to create the mask to remove the part inside the window. I'm going to make a PR to revert most of the alterations to the textures shader.

[SomeEmptyBox]

i was on this commit when everything was working as expected b0bae15 if that helps

[polluxcodes]

I'm 99.9% sure it is commit a5c1437 that broke it, so that lines up.

[polluxcodes]

Can someone having issues try PR #8971? It reverts most of the changes I made in the Textures.hpp file. If that works, it should be ready to merge.

I verified it works on AMD still, but don't own an Intel card to test on that.

[SomeEmptyBox]

i'm new to these thing, how can i check ? i have intel cpu with igpu

[cpiber]

@SomeEmptyBox How did you install Hyprland? You would need to check out that branch and compile from there. But I already did and it seems to be fixed

[SomeEmptyBox]

@cpiber did you check on intel ? then it should be fine, i use nixos and flake to install directly from latest git commit

[cpiber]

Yes, I'm on Intel, and I had the same bug on main @SomeEmptyBox

[polluxcodes]

@SomeEmptyBox @cpiber I think I know why this wasn't caught on my end. Can one of you try enabling blur when using the broken commit?

[cpiber]

I had the same suspicion, already tested with and without, no difference for me

[polluxcodes]

@vaxerski The fix is ready in PR #8971.
