Flameshot does not handle 4K well

[GXGOW]

Describe the bug

Whenever I try to take a screenshot with Flameshot, it only shows a quarter of the screen. More specific, the top left quarter of the screen.

To Reproduce

• Open Flameshot
• Click 'Take Screenshot' from the tray icon

Expected behavior

I should be able to take a screenshot of the full screen.

Desktop (please complete the following information):

• Model: Dell XPS 15 9560
• OS: Manjaro Linux (Gnome Edition)
• Integrated Intel Graphics are used (i7 7700HQ)
• 4K display
• Wayland enabled
• Flameshot version: Flameshot v0.5.1-90-gc75c9aa (Compiled with QT 5.11.0)

Workaround that Works For Me™:

unset the environment variables QT_SCREEN_SCALE_FACTORS and QT_SCALE_FACTOR, and set QT_AUTO_SCREEN_SCALE_FACTOR to 0 before launching flameshot.
It may also help to unset GDK_SCALE, GDK_DPI_SCALE, and/or ELM_SCALE.

Sadly, that did not change anything for me. Maybe the Wayland session has something to do with it too.

How do I implement this? Is there a way to put this in the .desktop file? If so, how?

I had this same problem, dual 4k displays on KDE in Ubuntu 18.04. Things wouldn't just look weird tho, the screen would get all super glitchy, like it "lost sync" or something. I would have to switch to another VT and kill the flameshot process to be able to see my desktop.

Right now I just have it wrapped in a simple shell script and that's how I start it.

I have 3 4k monitors running on KDE Plasma and this also did the trick for me. For those that come across this, you can do something like this in a script:

#!/bin/bash
QT_SCREEN_SCALE_FACTORS='' /usr/bin/flameshot &

The same problem, making scale by change system display settings.

Same here.

Model: Dell XPS 15 9560
OS: Ubuntu 19.04
4K display

Launching Flameshot with QT_SCREEN_SCALE_FACTORS works

QT_SCREEN_SCALE_FACTORS='' /usr/bin/flameshot &

The issue has been resolved for me.
Thank you for an awesome app and for the bug fix.

I still have this problem when using a docking station (laptop connected to 4k display)

tried starting flameshot via command line; with suggestions posted here; did not work for me.

QT_SCREEN_SCALE_FACTORS='' QT_SCALE_FACTOR='' QT_AUTO_SCREEN_SCALE=0 GDK_SCALE='' GDK_DPI_SCALE='' ELM_SCALE='' /usr/bin/flameshot gui &

You need to run flameshot with this and not flameshot gui. Then it should work
