• [X] This problem comes from a failure in the tiling system and not a missing feature

Describe the bug

From a fresh reboot.

Polonium causes the KDE desktop/windows to crash after adding vertical tile on vertical monitor if an active window exists. In addition, vertical tiling does not seem to work on a vertical monitor.

To reproduce

main monitor display = landscape secondary monitor = vertical

1. have an active window on the secondary monitor.
2. press meta+T
3. split vertically

Result = All windows crash

Vertical tiles don't seem to work in the vertical monitor, windows only align horizontally.

Expected behavior

ability to split vertical monitors in half where windows automatically scale and adjust to the vertical split.

Crashes almost as expected. Why would you edit the actual layout with Meta+T unless you're using the KWin layout? If you are, please specify, if not, don't change the amount of tiles on screen through KWin.

[smithmd]

What's the alternative to using Meta+T here? This crash is exactly why I stopped using it. A crash should never be an expected result. Should be handled somehow.

[zeroxoneafour]

@smithmd Handled by what? The script? The amount of control that the script has over KWin and its tiling is heavily limited. There's no exception to catch that when uncaught causes a crash, just random and unpredictable undefined behavior. One such undefined behavior is editing the layout when it is already being managed by the engine. While the script should just ignore the edits, sometimes KWin doesn't and throws a fit.

[smithmd]

Then again I ask, "What's the alternative to using Meta+T here?" Is the answer just that there's no way to manually edit the layout without potential crashes?
