spectacle w/ rectangular region and dual monitor moves display views

[imbezol]

Issue : When attempting to take a rectangular region screenshot with my 4k (3840x2160) monitor on the left and my 1200p (1900x1200) monitor on the right, spectacle first messes up the display views and then presents the rectangle tool. The view from my right monitor is displayed on the right side of the left monitor. The display from my left monitor shifts left 1900 pixels and is displayed partially, with the remainder off the left edge of the monitor.

Expected: Display views should not be moved and instead should remain on their own monitors and the rectangle tool should be presented.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[xerus (xerus2000)]

Still encountering this, it is super-annoying!

[Tristan Grimaux (tristangrimaux)]

I have the same problem. This does not happen with a big wide monitor

[thomas1187 (7tisix)]

Same here. I have Macbook with retina display, and bigger Apple display connected. When trying to capture rectangular region, a good portion of the screen is outside the boundary, and I haven't found a way to access that area to make my screenshot.

[Niko Storni (nikooo777)]

This bug affects me as well. I have 3 monitors: 2 FullHD and a 4K one.

Scaling is also set to a higher value than 1. Whenever I try to take a screenshot, everything shifts.

[Marco (marcorestom)]

It affects me too, i have 2 monitors: 4k + rotated FullHD

[Alessio Re (alessio.re)]

Same here with 3840x2160 (scaling 1.2x) + 1920x1080 (scaling 2.4x)

[Benjie Gillam (benjie)]

The offset is ~290px to the left for me (the far right is just 290px of white). I have three screens with their tops aligned, from left to right: 1440x2560 (rotated so bottom of the monitor is now to the left); 3840x2160; 1440x2560 (rotated opposite to first monitor). Ubuntu 18.04.3 LTS. I configured the monitors using NVIDIA X Server Settings.

[Severin Wünsch (sk1d)]

This also affects me I use scaling of 1.5 and a 1920x1080 and a 4840x2160 screen.

I guess this bug comes from the scaling factor. Before I used two screens with 1920x1080 px resolution and scaling set to 1 without any problems.

[Severin Wünsch (cioplenu-severin)]

I updated to Kubuntu 20.04 where I no longer have this bug.

[Bart (bart-schelstraete)]

I'm having the same problem on neon,20.04 and 1.5 scaling factor

[Andrey Shpak (insspb)]

Seems nobody cares :(
I am affected yb this too. Multimonitor setup

[lo-na-aleim (lo-na-aleim)]

I am facing the same issue. Arch Linux, Sepctacle 20.12.3.

@sk1d can you tell us the output for:

> spectacle --version

please? :)

[lo-na-aleim (lo-na-aleim)]

Just made an observation: Because I had to take a bunch of screenshots and wanted to use my big screens, I reset the scaling to 1.0 and rebooted. As expected, spectacle worked. Then I set the scaling back to 1.25 and re-logged. And spectacle still works! It even survived a reboot! I would encourage everyone to try that workaround and hope it aids in resolving this issue.

[Severin Wünsch (cioplenu-severin)]

As stated above currently I do not have the bug my version is:

spectacle 19.12.3

[Marco (marcorestom)]

I'm having the same issue on my dual monitor setup: 1080p and 4k with 1.2 scaling.

➜ spectacle -v
spectacle 18.04.0 - A Dearth of Dank Memes

Wow, 3 years and no solution yet!

[imbezol (travis-c)]

Maybe it will help someone, but I'm on 20.10 and no longer have this issue.
