External screens not available (until restart of Flameshot)

[tpcgold]

Flameshot Version

v12.1.0 (96c2c82)

Installation Type

brew install --cask flameshot

Operating System type and version

Soonoma 14.3.1

Description

Flameshot area doesn't extend to external screens when plugging them in.
So taking a screenshot or "selection" only involves the main display of the M2 Mac.

Tried to reinstalled etc. but the problem still occures (this problem exists since a few months)

Current workaround found: close flameshot and reopen -> but this is really annoying over time

Steps to reproduce

1. start Mac
2. add external Screen via usb-c/thunderbolt
3. problem occurs

Screenshots or screen recordings

No response

System Information

1. macOS Soonoma 14.3.1
2. Mac M2 with two Dell external Screens or Mac M2 with Samsung external Screen

Second this on Windows. Flameshot snapshots your multi-screen configuration on startup and then keeps that regardless of plugging or unplugging and moving to different setups with the device. Would love a fix for this.

seems the problem could be fixed by using:
https://doc.qt.io/qt-6/qguiapplication.html#screenAdded

(but I'm not a contributor atm. and don't have time to read into the code. just this trigger doesn't occur in the code anywhere , although it seems it should)
Also this trigger should occur:
https://doc.qt.io/qt-6/qguiapplication.html#screenRemoved

I can confirm that restarting flameshot on OSX fixed the issue for me.

EDIT: fixed it temporarily as @Saibamen pointed out.

fixed the issue for me

This is a workaround, not fixing

I'm trying today to apply the advice from #3505 (comment) and see if that works in general, if it does I'll link my pull request here. First impressions are good, but I'm not fluent in C++ or QT so I can't promise anything.

PR here but I don't know if it really really helps. You can try cloning my branch and building with

brew install qt@5 cmake
cmake -S . -B build -DQt5_DIR=$(brew --prefix qt5)/lib/cmake/Qt5 && (cd build && make)
open build/src/flameshot.app

@leehambley Tried it, it does detect the external monitor (even after unplugging and plugging again) 👍

However, it introduces a couple of regressions:

• The screenshot capture on the external monitor does not show any open windows. You can only screenshot an empty screen.
• It adds an additional window on the main monitor - to now dismiss the screenshot mode, you have to press esc -> click on the main monitor to focus -> press esc again.

Tested on MacBook Air M2 with 1 external monitor.

Came here to say that I love Flameshot but this has been bugging me for a while now. The most annoying part is when I right click on the taskbar icon to quit flameshot but I can only see the first menu item because the rest of it is off the screen. Would love to see some progress here!
