Scratchpad windows are always floating, so when a scratchpad holds more than one window they land stacked directly on top of each other. I keep a couple of always-on-top communication/media apps in one scratchpad, and every time I summon it I can only see the topmost window — the…

Add i3-style tabbed containers: a per-container layout mode where multiple windows share one tile's space, only the active window is drawn, and a thin tab bar switches between them. This mirrors i3/sway's layout tabs. Raised this previously in Discord with Lemmy, who indicated it…

When sharing a screen or recording a window stream during presentations, video calls, or live streams, users frequently need to protect their privacy by preventing sensitive applications (such as password managers, private chat windows, or notes) from appearing in the video…

Disconnecting the secondary monitor pushes all windows that were on the disconnected monitor on the first workspace of the remaining monitor. This is inconvenient and requires a lot of manual re-arranging windows around. My use case is that I use a laptop which I frequently need…

In dwindle mode windows open to the bottom or to the right. If you have followsfocus and you are at the left or the top half of the window, you can end up focusing the previous window by accident. The feature I'd like: . Existing layout behavior (scrolling, dwindle, master) There…

Some games like Path of Exile 1 & 2 might require FIFO constraints in order to work properly on native wayland. There is no workarounds. Wayland protocol support Commit-timing allows applications to set the earliest time the compositor should apply the commit. It can be used for…

When Umbriel opens a new window it spawns in the final screen position. But because the viewport is still focused on the old window it causes an overlap and a relative sliding motions between the windows. There is a similar overlap and relative motion happening with the closing…

wlr-randr can be used for run-time scripting to change display mode, position, VRR etc. without touching the config, but it can't get/set HDR info. Script to sed a separate config file. Doesn't work when my config is generated by Nix and therefore immutable. Also won't work when…

When I run CSD-style apps (Nautilus, gnome-text-editor, Evince), I get sharp square artifacts sticking out past the app's rounded corners, and all four edges glitch and flicker while I Super+right-drag resize. My SSD-friendly apps (nwg-look, terminals) are clean. The static half…

I use a magnifier daily — it's not a "nice to have" for me, it's how I actually read the screen. I'm used to KDE's built-in magnifier and COSMIC's full-screen zoom, and the moment I moved to Umbriel I lost that entirely. I tried wooz. It works, but it's a separate process I have…

I've got an idea, how about adding an "aspect ratio" window rule to make PiP windows stay 16/9 for example upon resizing. This way you prevent black bars and fiddling around with a window or some sort if "fixed aspect ratio" so of you resize a window, it will automatically keep…

PR #616 added the excellent blockcapture window rule so protected windows stay visible locally but disappear from screenshots and recordings. However, the same option is not available on layerrule. This means layer-shell surfaces (especially Noctalia notifications) still appear…

When I move a window to the scratchpad and then open/show the scratchpad, the window itself appears correctly, but its shadow is rendered with a noticeable delay. The shadow does not appear at the same time as the window, there’s a clear lag. 1. Open any window (e.g. a terminal).…

With title bars on, a tab moved out of its group to the scratchpad gets a title bar it didn't have in the group, but keeps the same content position. The title bar is added above it, so the window's top border ends up under the panel (or the bottom border off-screen). A normal…

With a fullscreen app on the active workspace, opening Vicinae displays its launcher above the app and the mouse can interact with it, but typing does not reach the launcher. Switching to a workspace without the fullscreen app makes Vicinae accept keyboard input again. Expected:…
