Screenshot of case 1)

STEPS TO REPRODUCE
1. Tile PyCharm 2025 to the left
2. Tile Dolphin or Konsole ro the right
3. Focus PyCharm's Window
4. Move the cursor from PyCharm's window to the center edge of the two windows

OBSERVED RESULT
Depending on the exact position, we get two different cursors / actions:
1) Resize PyCharm's window: This doesn't work, it only leads to a flickering PyCharm window, as it snaps back to the tiled position. Please see the screenshot.
2) Resize both tiled windows together


EXPECTED RESULT
1) Never occurs, only 2)

I could not reproduce this with other applications. Maybe it's a Java problem? or is there something on KDE Kwin side to fix?
