Shadow remains after window move with keys

[AlexJakeGreen]

If a window is moved using keybindings (e.g. Meta+Right), the shadow remains on old place.

It looks like something isn't being damaged enough but this would not be the responsibility of the decoration plugin, it should be fixed in whatever plugin you have configured to use i.e. Meta+Right. By default, it would be grid plugin. However it might not happen with other decoration plugins because they do not render shadows. Are you using the shadow plugin to render shadows or pixdecor with 'rounded corners' option?

[AlexJakeGreen]

I do not use shadow plugin. Here are the settings:

In your config, you have shadow_radius = 0, which means there are no shadows. Also in your screenshot, the window appears as if maybe it was wobbling or some other transform that make the lines not parallel to the edges of the shot. I am not able to reproduce this problem, so I feel like I'm missing something.

[AlexJakeGreen]

I used a phone, because an attempt to make a screenshot erases the artifact

[soreau]

Actually, when I set shadow_radius to a non-zero value, I can reproduce the problem. I'll look into it.

[AlexJakeGreen]

I think it was late when I tested with different shadow size, and set it to zero late night, and today just copied a part of config without recheking again. sorry. The shadow must be greater than zero. This is how I found it is shadow, not a border.

Does this wayfire patch help? It seems to fix the issue here.

[AlexJakeGreen]

Yes, the patch helps. The issue has gone after the patch applied. Thanks

[soreau]

I cannot say this patch will make it upstream. I am currently trying to find a way to fix it in pixdecor. I will leave this issue open until it has been resolved fully.

[soreau]

I was able to fix the problem in pixdecor, thanks for the report. This issue should close automatically when track-wlroots-0.18 is merged, so it will work without the wayfire/grid patch.
