SUMMARY I copied any picture in Gwenview, then I pasted this picture into the Mattermost chat, but two duplicate pictures appear. STEPS TO REPRODUCE 1. Open any picture with Gwenview 2. copy this picture in Gwenview 3. Past this picture in Mattermost chat. 4. See two same pictures, but not one picture. EXPECTED RESULT Please only one picture after inserting, not two same pictures in Mattermost chat. SOFTWARE/OS VERSIONS Linux: Manjaro KDE Plasma (Stable version) KDE Plasma Version: 5.21.5 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2
I checked this issue and know now: There are two different copy technologies: - Copy - Copy buffer Mattermost in Chromium works with both, that is why two of the same pictures appeared in Mattermost in Chromium. Mattermost in Firefox works with "Copy buffer" only, then one picture appereared in Mattermost in Firefox.
The issue was fixed.
