# unmapfullscreen ## Description This patch hides fullscreen clients by unmapping them instead of moving them off-screen. It applies to dwm 6.8. `showhide()` hides a window by moving it to `-2 * width`. Some games and Wine/Proton builds treat that as a broken or minimized state and do not recover fullscreen when the tag returns. With this patch a hidden fullscreen client is unmapped and mapped again when it becomes visible. dwm selects `StructureNotifyMask` on clients and `SubstructureNotifyMask` on the root, so calling `XUnmapWindow()` directly reaches `unmapnotify()` and unmanages the client. The patch adds a small `unmapclient()` helper that suppresses both masks around the unmap, the same technique the windowmap patch uses. Hidden fullscreen clients are not moved off-screen. The client tracks whether the patch unmapped it, which lets `showhide()` map it before restoring input focus without querying the X server on every arrange. Normal clients keep dwm's original off-screen hiding. A hidden client that leaves fullscreen is mapped off-screen again instead of remaining unmapped. ## Testing Applies and builds against dwm 6.8. Runtime tested under Xvfb. Hidden fullscreen clients became unmapped, stayed managed, mapped on return, and regained real X input focus. Tests also covered a new fullscreen client assigned to a hidden tag and a hidden client leaving fullscreen. ## Download * [dwm-unmapfullscreen-6.8.diff](dwm-unmapfullscreen-6.8.diff) ## Author * Daniel Guihot - [daniel@guihot.net](mailto:daniel@guihot.net)
