Taking screenshot on Dual UHD screen (7.680 x 2.160 pixels) not working correctly

[NickUfer]

Flameshot Version

Flameshot v12.1.0 (0bbb9528) Compiled with Qt 5.15.10

Command used for building:

cmake -S . -B build -DUSE_WAYLAND_CLIPBOARD=true -DUSE_WAYLAND_GRIM=ON && cmake --build build -j30

But this problem also occurred in 12.1.0-2 installed via apt.

Installation Type

Compiled from source

Operating System type and version

Kubuntu 23.10

Description

When I take a screenshot on a Dual UHD screen (7.680 x 2.160 pixels) it creates an editing view of 10.240 x 2.880 pixels.

• When I select the whole 10.240 x 2.880 pixels and save it to a file, the resulting image is only the actual 7.680 x 2.160 pixels of the screen.
• When I select a 600x600 pixel area to save, where all of it is inside the actual screen pixel range of 7.680 x 2.160 pixels, it saves the correct 600x600 pixel area I selected.
• When I select a 600x600 pixel area to save, where half of it is outside the actual screen pixel range of 7.680 x 2.160 pixels, it only saves the part actually in the 7.680 x 2.160 pixels area.

See screenshots for better explanation.

Steps to reproduce

1. Searching for "Take screenshot - Flameshot"
2. Clicking it

Screenshots or screen recordings

This is the screenshot that gets created:

But this is what I actually see and select (screenshot taken with Spectacle):

It increases the pixels from 7.680 x 2.160 to 10.240 x 2.880.

Same Problem for me. Its the screen scaling that shifts the capture screen. the shift size is dependent on the scaling.

Manjaro with KDE and two monitors
