Bug 433230

You can remove that window rule because Dolphin now always remembers its window size automatically. :)

If you don't want to remove the window rule, you need to make use of the window rule setting to override the app's own window geometry by also adding an "Ignore Requested Geometry: Yes" property to your window rule. This is made clearer in Plasma 5.21 when you create a window rule with with Size: property.

I made this window rule in case I would like to temporarily change Dolphin's window size, because I want Dolphin to have the same size every time I launch it.

I checked if it is true, and no. I removed the window rule and yes, Dolphin remembers its size, unless I maximize its window. When I maximize and return from maximization, Dolphin sets window size to this size, which I have shown in video. I have tried everything, also setting "Ignore Requested Geometry: Yes", and it doesn't work. Dolphin is still stubborn and after returning from maximization it sets its size to this fixed value, which I don't want.

I think there is either problem with Dolphin respecting Plasma's settings, or someone hard-coded this unwanted window size into Dolphin. Or some another problem, which I don't know.

And still there is problem with "Places" panel on the left side of the window, which changes width after returning from maximization. I don't want this behavior either.

Older version of Dolphin (20.08) didn't have those problems.

Thank you in advance for your help!

Perhaps this problem depends on size of window. My size of Dolphin window is 784x616.

Hmm, seems kind of like Bug 432661, but that was fixed in Frameworks 5.79 and yo have that.

If you remove your window rule entirely, does Dolphin restore to the correct position?

If not, does it do so if you temporarily move aside your ~/.config/dolphinrc file, restart Dolphin, and try a maximize+restore cycle again?

Position is OK. I have setting to place every window in the center of the screen. But size of the window is incorrect, regardless if I have a window rule or not. So no, if I remove this rule, Dolphin still restores to incorrect size of window. But I have noticed that if size of unmaximized Dolphin window is larger, more or less larger, this problem doesn't occur. But in my case (784x616) it occurs.

No, it doesn't help. It only makes Dolphin loss my settings, unless I restore that file into its place.

FWIW if your goal is to always position all windows in the center, there's a much easier solution than using Window Rules:

1. Go to System Settings > Window Management > Window Behavior > Advanced
2. Change "Window Placement" to "Centered"
3. Uncheck "Allow apps to remember the positions of their own windows, if they support it

Voila!

That's what I did. I was talking about that exactly.
I have separate window rules, but only the ones that control size of the windows of particular programs.

The second video showing this behavior of Dolphin in version 20.12.3

Because of the remainder about bug closing due to inactivity, I have posted another video, which shows this problem. Still doesn't work for me.

Finally, I have found, what is causing problem. In recent version of Dolphin you have moved URL navigator into the toolbar. Please, remove the URL navigator (breadcrumbs) from the toolbar, then it will appear under the toolbar. You will see, that Dolphin doesn't return into the window size set by you, when you return from maximize state.

That's not related to this, but if you're sure it is, you can test again by removing the "Location Bar" item from Dolphin's toolbar.

I have already tested this on new account in system (in order to eliminate other factors). When location bar is in the toolbar (default since Dolphin 20.12), Dolphin behaves correctly. When location bar is not in the toolbar, but under the toolbar (that's my setting, because I like that), Dolphin doesn't return to the desired size of window.

So it must be caused by placement of location bar. Or by something connected to the placement of this element of interface.

Can't reproduce, FWIW. In both cases, the restored window moves to the correct place. I did find one related problem while testing, however: Bug 434116.

I will try to fix that soon.

Perhaps the initial size of window matters? Please try to shrink your Dolphin window so that you have four columns of files/directories in icon view. I have such setup and in this case I can reproduce the problem every time.

I have to add, that in icon view I have icons of size 80 px.

The size of the window makes no difference for me.
