Created attachment 191279 [details] video of the bug, with audio. SUMMARY Hi, when using a graphic-tablet (eg. Wacom, here a XPPen), and hovering a task item in the Task Manager will display a tooltip or a windows preview. Problem: the preview/tooltip stay persistant, making the operating system experience difficult with a tablet. STEPS TO REPRODUCE (to do with a graphic tablet, a stylus) 1. Launch a software using the icon on the Task Manager (icon only, or long one with names) 2. Hover the icon to get a windows preview or a tooltip 3. Use the software OBSERVED RESULT The preview or tooltip will stay visible on the screen. If the user think the little cross on the corner is here to close the tooltip, it will close the software. EXPECTED RESULT When the cursor goes away, the preview or tooltip should disapear (fade away) as they do with a mouse. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Tested on Debian Testing KDE (plasma desktop 6.4.x) , reproducible on KDE Linux from today ( plasma desktop 6.7~2026-04-04 ), that's the one on the video in attachment, running as a liveUSB. ADDITIONAL INFORMATION I attached a video. Workaround: I would appreciate if someone can share one: eg. a command line that can turn off this windows previews or tooltips definitely, because this bug prevent me to migrate my soon EOL Debian 12 Plasma 5.x X11 to any KDE distro offering a Plasma 6.x Wayland right now, I'm a graphic tablet user and those persistent preview/tooltip are like always in my way and many time even obscuring. the toolbar and menu of my applications when I put my panel on the top. To make the tooltip disappear, I have right now to move the cursor with my tablet over an empty part of the panel. Can be very tricky when the panel is populated with many software open.
WORKAROUND: Go to the System Settings. Search for 'General Behavior' and disable the top checkbox in front of "Panel and widget tooltips" option. (Tips I got thanks to @redstrate on the 'KDE Input Handling' Matrix channel, works in 6.4.x and 6.7.x)
