gaps between tiled windows in various different situations

SUMMARY
It seems with the update to 6.0 setting the custom tiling padding to 0 doesn't actually fully set it to 0, there is still a small (1px?) gap between windows and window borders are visible on monitor edges.

STEPS TO REPRODUCE
1. Set custom tiling padding to 0
2. Tile windows into zones
3. Observe a tiny gap between two zones as well as window borders visible on screen edges

OBSERVED RESULT
Visible gap between windows when setting padding to 0

EXPECTED RESULT
No gap between windows when setting padding to 0

SOFTWARE/OS VERSIONS
KDE Plasma Version: 6.0.5
KDE Frameworks Version: 6.2.0
Qt Version: 6.7.1

ADDITIONAL INFORMATION
See attached screenshot for examples.
- Example 1 has a screen edge between the windows, the left window is snapped via *quick tiling* (moving window to screen edge to tile to half of the screen), the right window is tiled via custom tiling
- Example 2 is identical to 1, but both windows are tiled using custom tiling (shift + mouse drag) -> now the left window also has a border which is visible around the screen edge (which creates a double window border from both windows)
- Example 3 shows two windows tiled next to each other on one screen where a gap is visible (made more visible by a pure green image behind the two windows)

This didn't use to be the case in Plasma 5.27 for me, so I guess some regression since then?

Is any scaling used on your system?

No, I'm on 100% scaling on both my monitors

Not sure what more info to provide than what has already been given, happy to do so if something else is needed though.

Cannot reproduce with current git master on a screen with 100% scale. Let's assume it's fixed for Plasma 6.2. However if after upgrading to that version, you find that it's not fixed for you, feel free to re-open this. Thanks!
