Somehow the "close window widget" which is seen in the "Present Window" effect makes its way into the "Desktop Grid" Reproducible: Always Steps to Reproduce: 1. Activate "Present Windows - Current Desktop" 2. Hover over a window such you can see the "close window widget". 3. Activate "Desktop Grid" Actual Results: You can see, that each desktop includes somewhere a small window to close a window. The exact thing that the "Present Windows" effect is showing. I guess, the "Present Windows" effect doesn't remove this widget from some global window list or something.
Problem still persists in kwin 5.7.0.
Problem still persists in kwin 5.8.0.

I also observe this problem (Plasma 5.9.2 on Arch Linux). For me, I can't see the "close window" widget until I try to drag it [0] but it still uses up space. When I do grab it, it sometimes becomes visible though. Additionally, the "Buttons to alter count of virtual desktops" also show up in the same way (invisible until grabbed) if I enable them in the settings of the "Desktop Grid" effect. I think this bug is not too severe, but somewhat annoying since the "present window" layout becomes very weird due to the presence of so many invisible windows. [0] This might be related to bug Bug 361371, which I also observe on my system.
Is this going to be fixed any time soon?
(In reply to TYY331 from comment #7) > Is this going to be fixed any time soon? I don't think this has currently any priority. In fact I'm not able to reproduce which makes it hard to fix.
Git commit 558b86e9f6c08fde10933b3a3c7c126ba287c408 by Vlad Zagorodniy. Committed on 30/10/2018 at 20:39. Pushed by vladz into branch 'Plasma/5.14'. [effects/desktopgrid] Don't display the close button from Present Windows Summary: If you activate the Present Windows effect and then the Desktop Grid, you'll be able to see the close button from PW. The reason for that is PW doesn't destroy the close button and DG doesn't filter it out. This patch addesses this problem by syncing DesktopGridEffect::isRelevantWithPresentWindows with PresentWindowsEffect::isSelectableWindow. On X11, the close button is filtered by the isSpecialWindow check. On Wayland, the close button is filtered by the acceptsFocus check. The proposed solution is kinda hack-ish, but on the other hand, we have to keep those two methods in sync anyway. In addition to the close button, notifications won't be displayed too. FIXED-IN: 5.14.3 Test Plan: * Activate the Present Windows effect; * Activate the Desktop Grid effect; * (the close button is no longer visible) Reviewers: #kwin, graesslin Reviewed By: #kwin, graesslin Subscribers: kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D16513 M +25 -2 effects/desktopgrid/desktopgrid.cpp https://commits.kde.org/kwin/558b86e9f6c08fde10933b3a3c7c126ba287c408
