macOS flameshot only works on primary screen when there are multiple monitors in the same Space

[numeratorjik]

Flameshot version
265e42c on macOS Catalina

Describe the bug
If you have two monitors, and they're both in the same Space, and you tell Flameshot to take a screenshot, the secondary monitor goes black and you can only take a screenshot of something running on the primary monitor.

To Reproduce
In Mission Control, disable the option that creates different Spaces for your two monitors. Log out and log back in. Launch Flameshot. Tell it to take a screenshot.

Expected behavior
It should be possible to take a screenshot from either monitor.

System Information
macOS catalina

P.S. While this is annoying, I definitely want to say thank you so much for making Flameshot work on macOS!

[panpuchkov]

Please check it again, there're a lot of fixes for MacOS (especially for multiple displays) in the latest version (source code, not in the binaries yet).

[numeratorjik]

Problem still exists in current source code.

[panpuchkov]

Got it, I didn't read carefully and didn't check exactly your case.
If I understand you well, there is not menu in such configuration on secondary display and you cannot click on Flameshot icon and select "Take screenshot" on non-primary screen. I'll think about how to handle it.
For now you still have an option to use hotkeys. Move mouse pointer to the required display and press Command+Option+Shift+4.

[numeratorjik]

Hotkey does not help. The behavior is the same when I hit the hot key. It's always the primary screen for the space that is active after hitting the hot key, regardless of which screen my mouse is on when I hit it.

[panpuchkov]

I'll try to find somewhere Catalina, on a BigSur hotkey works fine for the described case.

I know about similar issue (capture primary screen only) on a systems with multiple displays after sleeping mode or connecting/disconnecting displays, which is reproducible just sometimes and on some systems, Flameshot restarting helps.

But this case is another one.

I am seeing the same behavior as @numeratorjik described but the Command+Option+Shift+4 hotkey works for me on either monitor. FWIW I am using 2 external displays connected to a 2019 MacBook Pro.

Edit: My 2 external monitors are not mirroring and I am not using the built-in display. Both of my external monitors are connected via DisplayPort on the monitor to USB-C on my MacBook.

[numeratorjik]

New information: Command+Option+Shift+4 doesn't work for me when I use a DisplayLink dock with two monitors connected to it, with one of the monitors mirroring the laptop's built-in display and the second monitor extending. However, it does work for me when I plug two monitors separately into my MacBook and there's no mirroring, i.e., the two monitors and the built-in display are all showing different content.

[bboles]

I still have the same hardware setup mentioned in my previous comment but have upgraded to Big Sur. Now the Command+Option+Shift+4 hotkey behaves the same way as clicking 'Take Screenshot' in the menu: a new blank desktop seems to be created on the primary display and the secondary display is blank.

[numeratorjik]

Interestingly, I see the above behavior as well, but if I quit from Flameshot and restart it and then immediately use the hotkey while a window on my second screen is focused, the right thing happens.
Just to be clear, I have both screens in the same workspace.

I have both screens in the same workspace as well.

Any fix on this? I'm on macOS BigSur (M1 macbook pro) and use a single mirrored monitor and when attempt to use flameshot it goes to a screen where I only see my background image (Desktop) and nothing else. Using version 0.10.1 of flameshot.

[panpuchkov]

Try please to restart a Flameshot and use hotkeys.
In some cases, after going to sleep or connecting/disconnecting an external monitor, the Qt library may lose other displays and I didn't find a way to refresh displays list.
Possibly it is fixed in the Qt6 (didn't check it yet), but have no time to migrate to Qt6 now.

[KyleStiers]

Using the shift+alt+cmd+4 hotkey? That doesn't work. Sorry should've mentioned I tried that when seeing it suggested above.

[nanggo]

On my macbook pro 16" also doesn't work multiple desktops.

When I using hotkey for capturing, flameshots start capture on new desktop (empty screen).

[panpuchkov]

Unfortunately, I don't have a MacBook right now, I'll try to reproduce it when it appears.
Actually Flameshot doesn't detect the active screen in MacBook terms, in Qt5 there is no such option. The active screen for Flameshot is the display where the mouse cursor is placed in.

This seems to work. If I connect to an external moniter and had flameshot open prior then I run into the primary display issue. However after restarting I have no issues even if I disconect and reconnect the external moniter. I guess the cavoit is this may break if another external moniter is connected or flameshot is restared without an external moniter. Using MBP 2016 Catelina.

@ThePurple My issue resolved that I reinstall flameshot.

[panpuchkov]

@nanggo thanks for letting me know.

I had this issue where when I tried to take a screenshot it would swipe over to a new blank virtual desktop ... I had to go set permissions, then restart the app and it was fixed. Not 100% if the permissions were the problem. ymmv :)

Perfect solution.

[bboles]

This issue is still present in version 0.10.2. @borgmanJeremy is there some reason this was closed?

[borgmanJeremy]

Unless I'm mistaken it's just a permissions issue.

[davisbug]

It's just a permission issue in Mac

I also was able to fix by uninstalling, installing again and selecting flameshot again in the Screen Recording section. For anyone else that may come across this issue in MacOS, depending on how you have Spaces configured in Mission Control you may only be able to activate flameshot on a particular external display by using the shift+alt+cmd+4 hotkey. Otherwise, flameshot will only activate on the main display if you click "Take Screenshot" from the application menu.

Thanks for the clarification @borgmanJeremy and @cellscripts !

I va set permissions correctly , and still having the issue. What i am missing?

Issue seems to match this description : "Try please to restart a Flameshot and use hotkeys.

Possibly it is fixed in the Qt6 (didn't check it yet), but have no time to migrate to Qt6 now." for behaviour at least. If restarted , stats working fine again.

thanks!

After an update, I had to remove the line stated in the above screenshots, then add it again and restart the app as asked by the MacOS. Now it works 👍 Thanks for this excellent tool

[m-stojanovic]

I managed to change screen focus by disabling screen recording permissions in macOS Security - Preferences ... and then enabled it again. With this, I changed focus on another display that I use more often—but still not working on both displays

Did it also and it works for me. But from time to time after the mac goes to sleep mode the functionality starts not working you need to just restart the app and it should work

[AymericFenschSepteo]

it doesn't work even after reinstall, delete from screen recording permissions, and reboot/restart application

I don't have the shift+alt+cmd+4 hotkey on my MacOS.
Thanks for your help.

[rewanthtammana]

Thanks, @rylincoln for #1258 (comment). It's helpful

It worked here. Thank you.

[BaasMurdo]

Uninstall & Reinstall worked for me today on Windows

[AlexanderMakarov]

On Macbook Pro 2019 I'm fixing it with "Quit" in Flameshot and launching it again. Fortunately, this issue is rarely reproduced and most times it starts capture on the "current focus" monitor.

[FlahDev]

I just revoked flameshot screen record permission, stopped the app, give the permission again, and stopped and reopen the app again.

Now everything works fine ˆ ˆ
