Summary: Instead of seeing the cursor <--> on the left edge you now see an icon that looks like |<- . This brings kwin decorations in line with GTK CSD icons. In theory this is also useful to tell which window will resize in the case of side-by-side windows (regardless of whether borders are on or not). In practice with the adwaita icon theme I tested with it's not very intuitive to realise which is which till you learn the icon. Change is more involved than it should be as Qt::CursorShape doesn't have these entries, and I don't want to shadow that enum internally or have to change kwin effect code. Specifics depend on cursor icon theme if they are not present it will fallback to the <--> icon. (Breeze does not have them currently) Test Plan: Resized some windows (on X and on Wayland) Correct icon appeared on Adwaita Existing icon appeared on Breeze Reviewers: #plasma Subscribers: kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D13396
