Description SkyWalteron 2025-08-21 11:37:05 UTC

1.Enable Split view in Dolphin
'dolphin --split' or Enable 'Configure/Interface/Folder&Tabs/New windows:Begin in split view mode'

2.Lost forcus of Dolphin.
Click on desktop Background or another window.

3.Refocus Dolphin, Exept tabs of left or right.
Click on the tab bar or toolbar or exept tab pain.

4.Press shortcut key, Back(Alt+Left) or Forward(Alt+Right) multiple times. 1,2,3,4.

Result:
Shortcut key action alternately on tab panes.
Back with left pane(A)→Back with right pane(B)→Back with left pane(A)→Back with right pane(B).

If click pane, normaly action to focus to panes.
But if happen this issue. Can't focus to panes with any click, shortcut keys.

Expected:
Shortcut keys do action to focus panes only.
Click panes to focus on panes.

This issue is no happen on older version Dolphin. Only 25.08.
This issue is random happen. But reproducible method with I wrote maybe.

I have the exact same problem. And I think it's also the same when you have a split view and use "places" shortcuts. They'll alternate between the 2 split views when clicking on them. Drives me mad. I'm on Arch/CachyOS BTW

Same issue here. If you have the terminal panel enabled you can workaround by (directly after starting dolphin) first clicking into the terminal panel and then into the left(!) split view After that this dolphin window seems to behave correctly.

I dont think I can reproduce this issue, did I try reproducing it correctly?

1. Open dolphin with `--split` 
2. Navigate through folders enough for the back/forward actions to be available, in both views
3. Unfocus dolphin
4. Focus dolphin by pressing "Places" panel
5. Press Alt+Left or Alt+Right multiple times

For me the actions only happen in the correct view.

Can someone make a video of this issue to help reproducing it?

Thanks for looking into that.
My steps for (a minimal) demonstrating the OP's problem description "Shortcut key action alternately on tab panes." are the following:

0. close all running dolphin instances

1. open dolphin in split-mode in some deep hierarchy, e.g.
    dolphin --split /sys/class/mem/full/power
    in the video I use: dolphin --split /just/some/deep/hierarchy/for/demonstration

2. dolphin opens with this path in both left and right views

3. press "ALT + UP-ARROW" (default shortcut for Go > Up) multiple times.

4. instead of going up the hierarchy in one split view, dolphins alternates between right and left view: go one up in the right view, go one up in the left view, go one up in the right view, ...

This is demonstrated in the attached screen recording.
Hope this helps.

I forgot to mention that in the second part of the video I use the mouse to navigate back into the deep folders in the right view. After that "ALT + UP-ARROW" behaves as expected.

Okay I can reproduce this now, very odd bug. Thanks for the video!
