--- Comment #19 from Juhani <[email protected]> --- Hello, I can confirm this bug on my system as well. Here are my system details: - Operating System: Fedora Linux 41 - Kernel: 6.14.6-200.fc41.x86_64 - KDE Plasma Version: 6.3.5 - Graphics Platform: Wayland - GPU: Intel Meteor Lake-P [Intel Graphics] (driver: i915) - Computer: ThinkPad T16 Gen 3 The system consistently freezes for 2-3 seconds with kwin_wayland spiking to nearly 100% CPU. This happens when I hover over the application preview or tooltip popup that appears after hovering a task manager icon. I have found a workaround by disabling the informational tooltips in System Settings. The freezes no longer occur after making this change. Steps to reproduce: 1. Use the default KDE Task Manager on a Wayland session. 2. Hover over an application icon to make a popup appear. 3. Move the mouse cursor over the popup itself. 4. The system will freeze, and kwin_wayland CPU usage will spike. Workaround: Disable "Display informational tooltips on mouse over" in System Settings -> Workspace -> General Behavior. This confirms the bug is likely tied to the rendering of these specific UI elements. Hope this helps. -- You are receiving this mail because: You are watching all bug changes.
