Rounded border on maximized window

[gabelluardo]

On maximized window, rounded title bar border show the background

This is an example with 20px border radius:

with the default breeza this doesn't happen:

I think it sets the radius to 0px on maximized windows

This is (perhaps was) a KDE bug, most likely fixed with #107, closing now.

This seems to have reappeared with Plasma 5.26

Not sure what you mean exactly. Do you mean when the titlebar is not present on maximization?

If so, please note that SBE here is intended to work different than Breeze as it keeps the borders. Just removing the titlebar including borders looks ugly (personal opinion), and round corners are consistent to this, SBE only removes the titlebar, but keeps all the rest: borders, outline, corners and shadows

[gabelluardo]

I mean the title bar is rounded even on maximization

[kupiqu]

If I understand you correctly, this is the intended behavior

If I understand you correctly, this is the intended behavior

would it be possible to make this optional?

[kupiqu]

I may consider revising a pull request...

but I am still confused about what you are exactly asking for. What is the behavior of maximized windows that you would prefer in terms of [titlebar (on/off), rounded corners (on/off), outline (on/off) and shadows (on/off)]?

I want that sierrabreezeenhanced disables rounded corners for maximized window

[kupiqu]

I may revise a PR if you convince me of why should regular users bother about rounded corners appearing in maximized windows in contrast to others.

[Syndrizzle]

It looks weird on no gaps, imagine seeing some space in the corner of your screen when your app is Maximized, even windows 11 doesn't keep them round...

[kupiqu]

Fair enough. I use (1px) gaps and small (3 px) rounded corners, with no titlebar on maximized windows and it looks good.
If you (or sb else) wants to work on this and submit a PR, I will revise it.

[Syndrizzle]

Only if I knew how to write C++ :(

[gabelluardo]

If you give me any suggestions on where to start, I can work on it

I am sorry, but I don't know about anything coming to my mind. I tried my best and I guess you can take a look at https://github.com/a-parhom/LightlyShaders/blob/c8e6b15abbb9918313fd1f76d040dd7e9380eed2/lightlyshaders.cpp#L222. That KDE rounded corners tool, it has 2 branches, the code is from main branch. Unfortunately, the main branch only works on plasma 5.25 and smaller, but refuses to compile on 5.26… the second branch works on 5.26, but relies on decorations like SierraBreezeEnhanced to provide the corners for it…. But since the main branch includes the toggle to disable for maximized window, it is possible to take a look at it.
