Have you tried this in a browser? Also are you using insecure HTTP over HTTPS? I also see a minified react error in the log, is the app running properly?

If all this is true can you take a video for me?

I can copy the regular text, but getting the same problems when trying to copy urls from messages. In on a windows 11 as well. I managed to understand the problem: if you move your mouse around, the selected text might change from blue to gray (dark theme), when the selection is of gray color, it won't be copied. If selection is of blue color, it will copy. I guess, it is losing focus somehow on mouse movement (not clicking anything)

UPD: it is losing focus when i hovering the urls

@devinbinnie Hello,

• As I wrote in the "Steps to reproduce", the bug only happens in Mattermost Desktop App, it does not happen in Mattermost opened in Web Browser.
• Indeed I use HTTPS (here is our organization link: https://chat.gameloft.org/)
• The app is running fine, I do not have any another problem apart from the "cannot copy/paste" issue mentioned above.

@Melodeiro Many thanks for your additional information 👍

@HaNguyenThu Can you reproduce the same issue on the community server? https://community.mattermost.com

[Gouvernathor]

@devinbinnie I do reproduce the same issue on the community server, at least on a link with integration.

@Gouvernathor Can you produce a video of what you're seeing?

[Gouvernathor]

The bug is not merely copy/paste, it's more widely the loss of focus on the text input box when hovering a link. I can't produce a video.

1. Go to a channel in which one of the last messages contains a link, preferably one with integration (I'll let you test whether that changes anything), and in which you're allowed to send messages
2. click on / focus the text box at the bottom
3. start typing gibberish with your keyboard
4. while typing gibberish, move your mouse over the integration and/or the link itself
5. despite continually typing on your keyboard, the text input box lost focus and the text inside stopped being written to, the instant your mouse hovered the link or its integration.

The copy/paste stuff is a bit harder to explain in simple steps like that, but I'm convinced it's the same bug. Basically it's as Melodeiro said : try selecting a part of a message (highlighting that part in blue), the moment your mouse hovers a link in the message, the selection turns grey and when releasing the mouse, Ctrl+C doesn't do anything. Right-clicking puts the focus back on the selected text, so the Copy option in the contextual menu still works.

[Melodeiro]

Yes, the source of the problem is a loss of focused state when hovering over any links in MM. And the most annoying part is that you can't copy the selected text after that because it's no longer focused.

[Melodeiro]

In the latest update, the behavior is even stranger: it rapidly switches between focused and unfocused states when I move my mouse. Note that I only clicked the mouse button at the beginning and end of the video. From 0:01 to 0:07 all i did was move the cursor.
