> When I win-left/right a window and then resize it, then close it, now win-left/right always resizes it as previous one. There’s no way to reset it to 50:50 (unless logout).

When you've win-left-ed a window, you've put it into a "zone", so what you're resizing is that zone not just the window. This is helpful when you've both win-left-ed and win-right-ed something so resizing via the split between them resizes both windows. (There's actually four of these zones with an up/down split too). You can reset it to 50:50 by resizing a zone-ed window again and your ratio with stay that way.

This is right, the “zone” is helpful for asymmetric side-by-sides. Windows does a similar thing.

The problem is that KDE “zone” doesn’t reset even when you close all windows associated with it, which should remove all traces of zoning cause there’s no window class/name affinity anymore. But when you win-left a new unrelated window, it becomes that-sized again. There’s no “reset” except for trying to manually 50%-width it back. My workflow includes taking screenshots (automation) so this is not an option, not to mention triggering perfectionism on “is this 50 or 49.7?”. I can re-size it to be around 50, but not reset (logout helps). I’d just bind a key “like everyone else does” ©, but there’s no way to control it programmatically.

I think I’ve seen a different thread last time, but here’s a similar one: https://discuss.kde.org/t/kwin-the-state-of-tiles/18316/3

Notably, it’s not how it always worked, it just broke with an update last summer (also affecting virtual screens etc) and no one seems to bother that much, as if it was some fringe “feature”.
