Tiled windows on right shift left

[yochananmarqos]

(1) Issue/Bug Description:

While I wait for my System76 Serval WS (serw12) replacment to ship out, I'm using my Dell Inspiron 5575. I wasn't using it that much until a week ago or so, so I can't say exactly when this started happening. I put this off because I usually am able to eventually figure problems out on my own, but this one has me stumped.

When tiling is enabled, the window(s) on the right will shift left slightly pushing the window(s) on the left with it. This happens about every 5 - 10 seconds. It will keep going until the window on the right has taken up most of the screen with the window on the left pushed so far over it probably reached the minimum width size. This occurs on both monitors as well as with the secondary monitor disabled. I've tried disabling all other extensions and tried both X11 and Wayland sessions.

(2) Steps to reproduce (if you know):

I've yet to figure out why it's happening.

(3) Expected behavior:

Tiled windows should not move once snapped into place.

What applications? Do you have a video to demonstrate how to replicate it?

[yochananmarqos]

Any application that's tiled together. I'm working through my extensions one by one to determine which one might be causing issues. It turns out just disabling them after being active isn't enough. After disabling them, logging off and back in I can't reproduce the issue. Now I'm enabling them one one allowing some time in between to play around.

One thing I discovered in the process that I may need to open a separate issue for is with Conky. While running, it causes windows to jump to different workspaces and/or monitors when toggling tiling or disabling / enabling monitors. This is my conkyrc.

Try with Dash to Dock disabled. This sounds similar to another reported experience.

[yochananmarqos]

It appears Dash to Dock is the culprit, indeed. Thanks for confirming.

[yochananmarqos]

It's not just Dash to Dock, it's also Conky that causes it. After a day of running things normally without Dash to Dock or Conky, I just fired up Conky and the issue immediately started again.

So really it's anything that fights Pop Shell for adjusting window sizes. Conky is it's own window and wants to push other windows out of it's way on the bottom of my screen. Dash to Dock wants to display on the left side of my sceen and have it's own space. That apparently freaks out Pop Shell, especially when both are active.

PopOS 20.10 Pop-shell v1.1.0~1615925109~20.10~77650a9

1. disabled all extensions (audio switcher, bluetooth quick connect, caffeine, clipboard indicator, dash to dock, emoji selector, freon)
2. open floating windows exception modal dialog (any modal dialog triggers the window resizing behavior)

I just updated it. Still 100% repro.

[rschuetz]

For Dash to Dock, the issue disappears if Dash to Dock has been switched to "Panel mode" (one big panel on the screen edge, with icons left/top aligned instead in the middle only, which looks unfortunately a bit ugly IMHO).

Btw, the tiled windows still shift to the left (and only to the left), even if the dock is on the bottom of the screen.

[alaborderie]

hey! I've made a post about this on reddit and got sent here.

I also experience this bug (You can find a video on the reddit post linked up there) and also happen to use Dash to dock!

I'll try disabling it later and will keep you updated if it still happens without it.

[alaborderie]

With Dash to Dock disabled in "Extensions" it looks good. I'll keep it disabled for now on my end, but would love to be able to use it again.

[spirkinator]

I've encountered this issue, too. It usually happens and is most easily repeatable on my dual-monitor setup running PopOS 20.04. No dock is enabled or installed. Open Gnome Tweaks, then set Workspaces -> Display Handling -> Workspaces on primary display only.

With tiling enabled, open at least 2 tiled windows on each screen. Initiate a pop-up in a program, then other windows will begin to shift left.

On my single monitor setup running PopOS 20.04, it happens less often, but can be replicated by opening 2 windows, then toggling Gnome Tweaks -> Workspaces -> Display Handling between the 2 options.

[jackpot51]

I believe this was fixed in https://github.com/pop-os/shell/pull/939 but will need to be backported for 20.04 and 20.10

[moniquelive]

I generally use 2 windows groups (stacks) side-by-side. Now the left-shifting of the left window group turned into a "auto 50% / 50% screen width groups resize". The trigger is the same: opening a pop window (eg.: open file dialog).

before: 1/4 & 3/4 sized stacks after: 1/2 & 1/2 sized stacks
