Flameshot v14.0 Release Notes

This release brings major improvements to multi-monitor support, fractional scaling support, new capture workflows, and a long list of bug fixes across all platforms.

---

New Features

Unified Approach to Multi-Monitor / Scaling

The largest change in this version is when a screenshot is taken, the user will be prompted to select which monitor to capture. Previously on Linux and Windows the capture widget was drawn across all monitors. This presents significant challenges as we diversify the DE's that are supported in linux and mixed scaling becomes more common. After a lot of testing and iteration I decided the best path forward is this solution.

I understand this is a change in workflow, and some may find it cumbersome. However, this will be the path forward for the time being. Please read the following sections as well if you are on X11 or Windows.

Additionally, on Linux the primary way to take a screenshot is using the xdg-desktop-portal calls. This is the only way to screenshot on Wayland, and many X11 DE's also support this. I reccomend looking at this Arch Wiki page to see if your DE supports it. If not there is a "deprecated" option that can be enabled that will fall back to the legacy method for capturing. (See below)

Legacy X11 Screenshot Fallback

For users on minimal window managers (i3, xmonad, etc.) without xdg-desktop-portal, there is now a Settings → General → "Use legacy X11 screenshot method" option that bypasses the portal. This is marked as deprecated but ensures Flameshot works in more environments.

Tray Menu to select screen

If you typically launch flameshot from the tray menu, there is a new dropdown that will directly let you select which monitor to capture and bypass the monitor selection widget.

Capture Active Monitor (X11 & Windows)

When this is enabled Flameshot will skip the monitor selection dialog entirely and will automatically capture whichever monitor your cursor is on. Enable it in Settings → General → "Capture active monitor (skip monitor selection)".

⚠️ Not available on Wayland due to security model limitations.

Windows Global Screenshot Shortcut

Flameshot on Windows now supports a global "take screenshot" hotkey, meaning that you can now take screenshots with keybindings other than PrntScn. It can also detect if Windows has reserved PrtScn for Snipping Tool and offers to change that registry setting, or register Flameshot as the system's screen capture application.

D-Bus Capture Method (Linux)

A new captureScreen() D-Bus method lets scripts and external applications trigger Flameshot's GUI capture programmatically, making automation and integration even more easier on Linux.

Portable Binary Mode (Windows)

Flameshot can now store its configuration in a flameshot.ini file alongside the executable instead of the user config directory. This enables portable/USB-stick deployment. Controlled by the USE_PORTABLE_CONFIG CMake flag (on by default for Windows).

Screen Subcommand Redesign

The flameshot screen CLI subcommand has been reworked to support a per-screen capture paradigm. A new --edit/-e flag enables the user to specify which screen to capture. Users can use this to bind custom hotkeys to screenshot specific monitors to bypass the monitor selection widget.

Nix Flake Support

A comprehensive flake.nix is now included for reproducible builds and development on NixOS. Use nix build, nix run, or nix develop out of the box.

Improvements

Launcher UI Made More Compact

The launcher dialog is now significantly smaller: monitor selection is hidden on single-screen setups, layout margins are tighter, and the window auto-fits its content.

Update Checker Rework

The update notification system has been overhauled. The menu now shows "Download version X.Y.Z" when an update is available. Manual checks display "You have the latest version" when up to date, and the UI updates smoothly without requiring a menu close/reopen.

New macOS Icon Set

The application icon on macOS has been replaced with a higher-quality, multi-resolution icon set.

Removed Startup Delay

The 500ms arbitrary delay on the desktop entry's "Take Screenshot" action has been removed. This was exclusively affecting some Linux users and was initially meant for older version of Unity DE.

Bug Fixes

Wayland

• QPainter crashes on KDE Plasma Wayland (Qt 6): Added safety checks across 9 widget files to prevent "Paint device returned engine == 0" crashes when the backing store isn't ready.

• Clipboard runtime detection: A single binary now works on both Wayland and X11 — the clipboard backend is selected at runtime instead of compile time.

• GNOME clipboard copy failure: Worked around GNOME's requirement for a visible window during clipboard operations. The capture window now stays briefly alive until the compositor fetches the data. (Fixes [#4116], [#4298])

Cosmic Desktop

• Fixed capture window not going fullscreen on Cosmic DE.

X11 / GNOME

• Fixed crash caused by Qt::BypassWindowManagerHint on X11 GNOME.

Windows

• Forced PNG clipboard format on Windows — the JPG option caused compatibility issues and is now disabled.

macOS

• Fixed copy-to-clipboard not working when invoked from the terminal.

Cross-Platform

• D-Bus hang fix: Flameshot no longer hangs on systems without a org.freedesktop.Notifications service registered. (Fixes [#4353])

• D-Bus race condition: Fixed a race condition where a temporary QApplication could corrupt Wayland connections, causing subsequent portal calls to hang.

• Double right-click segfault: Fixed a crash caused by double right-clicking in the capture window.

• Last region on scaled displays: Saved region coordinates now correctly account for the device pixel ratio on HiDPI screens.

• Layout warning fix: Removed a duplicate layout parent assignment that printed a Qt warning on every capture.

---

Packaging & Infrastructure

• Dropped support for Ubuntu Focal; bumped minimum dependency versions.
• Added Windows installation instructions for Scoop.
• Added instructions for setting the screenshot hotkey on GNOME when installed via Flatpak.
• Updated Flathub badge and GCC version requirement.
• MacOS intel build is no longer included. The CI was producing binaries users reported as not working in the beta and I have no ability to troubleshoot it

---

Translations

• 19 translation updates via Weblate, including improvements to Spanish, Finnish, and many other languages.
