Flameshot region capture shows tiny image when on dual monitor and/or screen scaling

[haizaar]

Flameshot Version

flameshot-12.1.0 (amd64)

Installation Type

Nix

Operating System type and version

NixOS with KDE 5.25.3 on Wayland

Description

Since some recent upgrade region capture is not really useful with flameshot:

1. It shows both of my screens
2. But makes everything very small. I.e. both my 27" and 14" screen capture are displayed on half of my 27" screen.

Beforehand it only captured one of the screens but was working well in that. Now it captures both screens but it's not really useful - too tiny.

Here are my screens before capture:

And here is how capture UI looks:

My screens configuration is below:

Steps to reproduce

1. Run flameshot
2. Click on its systray icon

Screenshots or screen recordings

No response

System Information

• NixOS unstable

Please consider:

1. provide full information (for example, you didn't mention if you are on Wayland or not)
2. write a better title for the issues. The title should contain the problem, not a general complaint

I would be thankful if you fix these.

Update: Since you have mentioned that it might be related to fractional scaling, please also check if the issue is fixed when you put every monitor on 100%. This can help us identify the issue.

[haizaar]

Thanks for your feedback. I've updated the title and added "wayland" in description. Is there anything else you believe is missing?

The issue can be triggered either by 200% scale on a single/dual screen, or by just dual screen in general (even when both are on 100%). Here is the summary of my tests:

• External screen only 27" 2560x1440 @ 100% - works fine
• Laptop screen only 14" 3840x2400 @ 100% - works fine (this setup is not really usable in general)
• Laptop screen only 14" 3840x2400 @ 200% - broken as per my report. The captured screen is shown on the quarter of the monitor
• Both laptop and external monitor, both at 100% - broken as per original report. This time the captured screen is shown on the laptop monitor

Same issue here, is any update on this?

[ProfessorSniff]

also encountering this issue, arch kde. scaling is at 150%, and 100% isn't practical on a laptop screen.

this issue first started happening several weeks ago, before that, it was fine. it seems like something changed, but i'm not sure if it was here or in kwin.

I have the exact same issue using Windows 10 since I updated to 12.1.0

I believe I'm also seeing this issue on MacOS

MacOS 12.6 Flameshot v12.1.0 (96c2c82e) (I believe I also saw on v12.0) 2 displays - Primary 4K external monitor, secondary macbook pro screen

This is a duplicate of #564

[haizaar]

I'm not sure it's duplicate - it happens on 100% scaling as well when on dual monitor setup.

[Avimitin]

I don't think this is duplicate. Actually flameshot is working, it just shrink all the visible screen sizes and make it hard to select capture area. And it also happens on 200% scaling, which is not fractional scaling. I suspect that this is more like misused of multiple screen API.

[mmahmoudian]

I reopened this due to the last two comments.

@Avimitin would you please also provide your system info and installation method and Flameshot --version

[Avimitin]

I am running flameshot on Arch Linux, with KDE + Wayland environment. The flameshot executable was installed via pacman, and here is the version information.

Flameshot v12.1.0 (-)
Compiled with Qt 5.15.5

Here is how it looks like when I run command flameshot gui:

Also there are some extra logging when I run the flameshot gui command:

qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()

My display settings:

[Chryseus]

I'm also having a very similar problem, using Arch with KDE Wayland as well, both monitors are partly merged together and displayed on the primary display, scaling is 100% on both.

Display setup:

Also getting qt.qpa.wayland: Wayland does not support QWindow::requestActivate() as well.

[ThatFruedDued]

Same issue on Arch with KDE Wayland, scaling set to 125%. Running Flameshot v12.1.0. Getting same qt.qpa.wayland: Wayland does not support QWindow::requestActivate() as others here. Problem did not occur for me on 100% scaling, only started appearing when I switched to 125%.

@ThatFruedDued

Problem did not occur for me on 100% scaling, only started appearing when I switched to 125%.

That is an issue with fractional scaling. Is 200% also problematic?

[ThatFruedDued]

That is an issue with fractional scaling. Is 200% also problematic?

Yes, 200% scaling has the same issue, where the image appears in the top-left corner. 100% works fine.

[shitan198u]

im also facing the same issue on any scaling the capture window becomes tiny it doesnt happen in 100% scaling

[sung-kim]

+1 I'm facing the same issue on MacOS 14.2.1, info from flameshot "About" menu:

Flameshot v12.1.0 (96c2c82e)
Compiled with Qt 5.15.5
darwin: 23.2.0
osx: 14.2

[HEIlZMaker]

This bug occurs with a laptop and the integrated screen at scale 125%. testing 100% fixes the issue but that is not viable for a tiny laptop screen

I am running debian 12 KDE

installed via "sudo nala install flameshot" The output of flameshot -v is: Flameshot v12.1.0 (Debian 12.1.0-2) Compiled with Qt 5.15.8

(screenshot taken with the flameshot bug)

I hope to see the bug fixed. I very much like this app

While writing this report i encountered a related bug: while attempting to take a screenshot of what it looks like I ended up with a vastly different result to what I saw in the preview In the following picture I took a screenshot of my entire screen. Note the visible github content is only about 25% in the preview IE the bug is that the preview is not displaying the capture accurately however when taking a full screenshot things are sized as expected

if you want clarification or have questions please ask. I this is my first bug report

[tirtharajsinha]

This issue is still there and have not fixed.

[floshipper]

Same issue on macos remains

[SwapnilSoni1999]

Same issue still remains even on single screen with wayland on arch with KDE plasma 6 that too with a single screen (I only have my laptop)
