I've noticed that this happens with self-made snapzones too. More specifically, I find that there's a 1px empty space on the right side of my screen. This seems to happen with mostly UWP apps and apparently only when using scaling other than the recommended one. E.g on my Surface Laptop 3 15": no gap on recommended 150% scaling, but 1px gap on 125% scaling.

I have default scaling (100%) and the problem still persists even with default template (2 columns). My screen has 2560 x 1440px resolution.

The current workaround for me on a 5120 x 1440 monitor with version v0.33.1 is to set "show spaces around zones" to ON and the associated value to -2.

[rodneypantonial]

On a 4k Monitor, it can work well with the following settings:

• -1 for "show spaces around zones"
• Settings > Personalization > Colors > Title Bars and Window Borders (Checked).
• Advance System Settings > Performance > Show Shadows Under Windows (Unchecked)

Also noticed 1px line between window and Taskbar (2560x1440). Workaround -1 for "show spaces around zones" works, thx.

I have the same problem on my 2560x1440 screens. The -1 or -2 workaround works, but also puts some pixel of the windows in the zones on adjacent screen which look even worse. Would really love to see this fixed

[davidrapan]

Its certainly not ideal but as Im using it only to bridge the gap from TaskBar aka in that "Priority", it does not have any issues i know of.

I also have this problem and would normally resolve is davidrapan does; adding a negative gap.
That solution is not available for Canvas layouts however, and thought I would mention that lest canvas layouts be forgotten in this discussion.

Thanks for a wonderful tool!
