SUMMARY There are three problems here: 1. When dragging a chromium tab (not window!) the dragged tab will not be focused until it's dropped. (So basically if another window is focused and you start dragging a tab from a chromium window that isn't focused, then that dragged tab will be dragging below the focused window.) 2. Sometimes chromium tabs merge with a window that is covered behind other windows. Unfortunately this only happens sometimes and I haven't yet found a way to reliably reproduce this. 3. When a chromium window is tiled to the left/right half of the screen and you start dragging a tab from it, then that dragged tab will remain glued to the top and bottom of the screen during the dragging. EXPECTED RESULT 1. The dragged tab should become focused with the begin of the drag. 2. Tabs shouldn't be able to merge with windows that are covered behind other windows. 3. The tab dragging experience should feel like the tab is sticking to the cursor.

1. + 2. : cannot reproduce on git-master. Have never seen that in any case. It could be that it will be fixed in next major release or it is an issue in Fedora. It would be interesting if you can reproduce it on something like the Neon unstable live image. It contains the most recent KDE version. If you want to check out what the team has been working on this could be interesting for you (lots of awesome improvements imo). 3: not entirely sure what you mean, but it sounds like a Chromium design choice. Maybe enabling the Wayland display system in Chrome improves your situation? Setting chrome://flags > Preferred Ozone platform to "Auto". I am using it but it is in beta and has its issues.

Thanks for the bug report! Unfortunately it reports multiple distinct issues, which will make it not actionable. See https://community.kde.org/Get_Involved/Issue_Reporting#Multiple_issues_in_a_single_Bugzilla_ticket for more explanation. Can I ask you to submit a new bug report for each specific issue? Thanks again!
