Glitch when moving windows on bottom window corners

[ramon501]

here it was up to date til fix 53, then ran git pull to get all updates and now i have glitches when moving windows, didn't have this issue before

[xaqbr]

same here. im hanging on an older commit til then

[a-parhom]

Could you, please, provide video of the issue? Also, please, tell which Plasma version do you have?

The screentearing is from the video, recording with opengl did not work for me, disabling wobbly windows effect helps a lot but i still have glitch when closing windows plasmashell 5.25.4

[zetastormy]

Same happens to me, but with some little differences:

As you can see in the right side of the Konsole window, the outline appears to be scaling at the same time as the opening and closing animations happen. Also running KDE Plasma 5.25.4

[p0ryae]

I don't use this feature personally, But I can also confirm the same issues happen to me when enabling it.

KDE Plasma 5.25.4 Is what I'm running.

These animation effects can not be supported with current version of LightlyShaders, unfortunately. It is limited by the currently used approach of shaping corners and drawing outline.

The good news is that I'm working on another version, LightlyShaders 2.0, so to speak, that will use different approach which will potentially fix this and other issues of working together with other effects, as well as significantly improve performance. In some days I'm planning to push it to a separate branch. It will be still work in progress and may contain bugs for some time, though.

I'm looking forward to 2.0!

[p0ryae]

Great! the current version is really great other then a few minor bugs which can be ignored by the user for now.

we appreciate your work and we are all looking forward into 2.0 👀

But it's not complete yet, things may break or just not work.

[p0ryae]

But it's not complete yet, things may break or just not work.

No worries. Going to give it a test myself right now.

[p0ryae]

Okay wow. It's actually much improved compared to v1.0 in terms of quality of the roundness. It's less pixelated. No issues encounter so far with v2.0.

However, There is a feature missing and doesn't seem to work, and that is the outline. It doesn't seem to be appearing for me.

[a-parhom]

It's not implemented yet, I've mentioned that in the readme for branch v2.0.

[p0ryae]

Just noticed. Thanks for clarifying.

It'll be nice to have the ability to force the corner radius on the Window Decoration chosen. On my Sweet-Dark Window Decoration I'm missing the top area's corner radius, which is not in sync with the radius chosen in the LightlyShader 2.0:

[ramon501]

How do i switch to the new branch ?

How do i switch to the new branch ?

It's not recommended to switch to at the moment based on the dev, but if you're impatient and can't wait, use git to clone the repo, and then switch to v2.0 branch. (git switch v2.0)

In v2.0 we will have to rely on decorations, that correctly deal with korner bug (since Plasma 5.25) and have an option to adjust radius. You can try SierraBreezeEnhanced to achieve similar results as on your screenshot.

[ramon501]

Just switched to branch v2.0, working great here

[a-parhom]

The reason for this limitation is that the new approach, which gives us full compatibility with other effects and very good performance, doesn't give us access to modifying blur region in the titlebar area. Only window decorations have access to it. And though it looks like it's possible to cut top corners and interpolate shadows underneath, the blur will still be there, and we will have "korner bug 2.0".

[p0ryae]

Fair enough. SierraBreezeEnhanced is much more customizable then other window decorations and I never had any ideas that it existed to begin with.

Thank you once again.

Great work. Thanks a lot! I'll be waiting for the outline icing on the cake.

Great work. Thanks a lot! I'll be waiting for the outline icing on the cake.

Outline implemented.

[p0ryae]

Outline implemented.

Amazing work! Just tested it and it works neatly. No bugs experienced other then sometimes the border lines might just leave some prints on the screen occasionally, but it's much better handled then v1 for sure.

[ramon501]

I didn't have luck with the latest commits, looks like kwin_x11 keeps restarting all the time on a non-stopping loop, i had to log on a xfce session to uninstall LightlyShaders

Thank you so much! It looks great!

That is weird. Could you give some details about your configuration?

[ramon501]

I tried to install it again but i had no compositing on plasma this time even not on restart, i had to re-enable compositing from systemsettings, i'll leave the output of the install here

[a-parhom]

Could you please tell me what window decorations do you use?

[ramon501]

I use Styleproject

[a-parhom]

I've fixed the nullptr reference error, but looks like Styleproject is not compatible with current KDecoration shadow API, so the outline is not going to work properly with it.

[ramon501]

Thanks, the last commit helped a lot, no more crashes, i don't use the outline feature so that's fine for me

[ramon501]

I use the no border kwin option for firefox, now i noticed if i do this the rounded corners are gone, maybe this is related to styleproject ?

[a-parhom]

I think it's possible. You can try SierraBreezeEnhanced decoration, for example, just to figure out that. Also, it is highly customizable and fully compatible with LightlyShaders (except squircled corners for now, but I'll consider implementing that and making a pull request), so maybe it will do the job for you.

[ramon501]

Ok, i'll try a test, until yesterday i could use the no border on firefox just fine and the rounded corners would still work, i do that on every session instead of creating a permanent rule, the reason is if i create a no border rule for firefox the shadow around the windows is also gone and if i just use the no border option after launching firefox i get both rounded corners and windows shadow

[a-parhom]

2.0 code is in master branch now.
