reproduction with dolphin
Can reproduce with the configuration shown in the video -- with a bottom floating panel set to always visible. There are two things going on here: 1. with unrestricted move-resize the window can be moved completely offscreen 2. windows that are completely offscreen don't show up in gridview/overview/present windows Note that the window can still be reached via the tabbox. A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/5604 Git commit 1a4606d990b89f403e048edef4b07b407b94a370 by Yifan Zhu. Committed on 11/04/2024 at 16:36. Pushed by fanzhuyifan into branch 'master'. scripting/windowmodel: match screen closest to center for filter When filtering windows by screen, match the screen closest to the window center, instead of testing whether the window is visible on the current screen. The new method guarantees that when filtering by screen, the window appears for exactly one screen. Previously windows spanning multiple screens appear on all of them, and off-screen windows are not shown in any screen.

Created attachment 168351 [details] reproduction with a firefox window SUMMARY Stumbled on a way to drag a window just under the bottom the display. It then doesn't appear on the overview or desktop grid effects. It can't be reached using the mouse, since the cursor can't go there. Looks like an off-by-one error between the cursor and the window's positions. STEPS TO REPRODUCE A. With firefox 1. Open a firefox window, and maximize it. 2. Push the cursor to the top of the screen. 3. Click and drag the cursor to the bottom of the screen. B. With dolphin 1. Open a dolphin window, and maximize it. 2. Push the cursor to the top of the screen. 3. Drag the window using Meta + left click. 4. Push the cursor to the bottom of the screen. OBSERVED RESULT The window is completely hidden. There is now no way to interact with it using the mouse. EXPECTED RESULT The topmost line of pixel of the window should still be visible on the bottom of the screen. The window should still appear on the overview effect or the desktop grid.
