2. Disconnect monitor 2.
3. Startup Telegram.
4. Connect monitor 2. Windows will automatically move MainWindow to monitor 2.
5. Click on a photo or a gif to preview.

Expected behaviour

MediaView shows on monitor 2.

Actual behaviour

MediaView shows on monitor 1.

Configuration

Operating system: Windows 10 1803

Version of Telegram Desktop: 1.3.14

I have same issue with Telegram Desktop 1.3.14 on Linux (Linux Mint 18.3)

[smeshny]

I have same issue with Telegram Desktop 1.3.16 Alpha on Windows 10. To fix this problem u need drag telegram window to second monitor with opened image and drag it back.
Very annoying issue...

[poschi3]

I have the same Issue with Telegram Desktop 1.4.3 and 1.4.4 Beta on Linux Mint 18.3 Cinnamon

[doubledare704]

In telegram 1.4.3 with Ubuntu 18.04.1 still appearing to another display even with dragging telegram window to display with image and dragging back

UPD I've switched primary display to another for Ubuntu (I have 3) and 3rd was chosen one and it opens media on same display now. Maybe it would help.

[poschi3]

I still have the problem with Telegram Desktop 1.5

[kode54]

I have the problem now with Telegram Desktop 1.5.2 on Ubuntu 18.10, using Wayland.

[Cyberuben]

I have the same issue on Windows with version 1.5.2

[malucious81]

I am having this issue on Fedora 29, gnome desktop. Telegram version 1.5.2
Edit: This does not occur the first time I open an image, when telegram is freshly launched. Only on the second image and onward.

[kode54]

I am having this issue on Fedora 29, gnome desktop. Telegram version 1.5.2
Edit: This does not occur the first time I open an image, when telegram is freshly launched. Only on the second image and onward.

I can confirm this on Arch. I can also report that it does not occur with Plasma / KWin.

[ice-bit]

Same issue on Arch Linux with version 1.5.4(latest version).
As @malucious81 said, this bug appears only the second time you open an image.

[nexusriot]

same issue mint 19.1

[dadee]

same issue win7 x64 1.5.4

[HamishMacEwan]

Similar issue with Windows 10, Telegram opens on the secondary not primary monitor and its awkward (alt-space, "M," arrow, mouse move) to put it back on the primary where it was during close down.

[tzurbaev]

This issue was fixed for me (Ubuntu 18.04; media view window was displaying on second monitor) after v1.5.11 release. I'm not familiar with the tdesktop's codebase but this change might be the one that fixed this.

[GoldsteinE]

Same, Arch Linux + i3wm, Telegram Desktop 1.5.12

[poschi3]

I still have the problem with Telegram Desktop 1.5.11 and 1.5.12 on Linux Mint 18.3 Cinnamon

[malucious81]

The issue is resolved for me on version 1.5.11 still on Fedora 29 Workstation.

[Kreozot]

Expected behaviour: I can move preview window on any monitor I want

[kode54]

I am having this issue on Fedora 29, gnome desktop. Telegram version 1.5.2

I can confirm this on Arch. I can also report that it does not occur with Plasma / KWin.

And now I can confirm it's fixed on Gnome, but now broken on Plasma / KWin.

@kode54 .. and that's all you need to know about UI development for Linux 🤣

[b1oki]

Has two displays, Primary left №1, second right №2.
Media popup opens on №2 everytime.

• Linux Mint 19.1 Tessa (based on Ubuntu 18.04) with Cinnamon _link_
• Telegram Desktop 1.6.3-6-g9b247ce (from snapd)

What about #5615, it's same problem or not?

Some Problem here.

Telegram Desktop 2.4.6
Linux Mint 20 Cinnamon

Primary right, secondary left.
Telegram is on the primary.
Media popup opens on secondary every time and locks the telegram window.

And when I use "Move to the other monitor" in the taskbar, this setting will be ignored the next time i open the media viewer.

The Telegram main window is locked, when the media viewer is opened, so the media viewer should open on the same monitor like the telegram main window and its better to not lock the main window for better work flow.

The algorithm seems to be valid, I don't understand why this happens at all

What else can I show?

I have no idea. This seems to be a Qt/Cinnamon/gfx drivers bug, since the tdesktop code just sets the same screen that main window uses.

Ok, and now? Who should we contact? A solution would be great, because this bug is very annoying in my daily work...

And I see some people here have this problem also in Windows 10.
So not only Linux / Mint / Qt / Cinnamon Problem.

Only NVIDIA? Or AMD / Intel too?

[ilya-fedin]

And I see some people here have this problem also in Windows 10.

As far as I'm understanding, there mixed three issues:

1. Qt doesn't handle the screen change when a screen is connected on Windows and Windows automatically moves the window to that screen, so that it is necessary to move window to another screen and back (there were multiple Qt updates, the last one is at 2.4.8, so maybe not an issue anymore)
2. Wayland doesn't have a protocol to specify window position, so that media viewer is appearing on the screen compositor is chosen and not tdesktop, that's the cause on GNOME Wayland. Unfortunately, no way to fix since there's just no such protocol.
3. Some weird issue on Cinnamon, I can't reproduce that on a VM, media viewer successfully opens on the right screen.

[ilya-fedin]

Who should we contact?

Qt or Cinnamon developers. I don't know on which side the bug so I don't know who you should contact.

[hanthecat]

Still having this issue 2 years later. Telegram windows desktop v2.47. Would it be possible to add something to the right click context menu and ask the user where they want the window to open?

[ilya-fedin]

@hanthecat this issue is about media viewer, not about context menu

[snitko]

Tip for those using Telegram Desktop on i3wm:

1. Open the media. If it opens on the wrong dislpay, that window is still going to be in focus.
2. Hit the key combination to move it to the scratchpad.
3. Move your focus to the display you'd like it show on.
4. Hit the key combination to bring it out of the scratchpad and it will show as a floating window on your current display.

[amatas]

Could it be possible to change the behavior of the media viewer to use the full window of Telegram as view space instead of the full screen?. This could solve this issue, and also it would be less invasive at any desktop interface. (I don't like to hide other windows if I'm watching a media in Telegram)
