            Bug ID: 1051306
           Summary: kwin: horizontally maximizing window and unmaximizing
                    it makes it grow by 8 pixels
    Classification: openSUSE
           Product: openSUSE Distribution
           Version: Leap 42.3
          Hardware: x86-64
                OS: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: KDE Workspace (Plasma)

I started to encounter this problem after upgrade from 42.2 to 42.3. Steps
to reproduce:

1. Make one window maximized only in vertical direction (e.g. by middle click
   on the "maximize" button) and check its geometry with xwininfo.

2. Maximize the window horizontally by right-clicking its "maximize" button.

3. Restore the geometry by right-clicking its "maximize" button again.

4. Check the geometry with xwininfo.

Result: the position of window's top left corner is preserved, its width is
larger by 8 pixels. This is especially annoying for windows aligned with
right edge of the screen because maximizing and unmaximizing the window makes
the window grow beyond screen edge.

Notes:

- horizontal position doesn't seem to matter; reproduced with windows aligned
  to left screen edge, aligned to right edge or somewhere between
- the window must be maximized vertically; when it's not, its size is restored
  correctly (including windows aligned with top or bottom screen edge)
- reproduced on two machines, one with a single 2560x1440 monitor, one with
  two 1920x1080 monitors (combined into 3840x1080 workspace)
- 100% reproducible (on my machines with 42.3, that is)
