Windows 10 UWP Not Rendering Fully

by Phillip McMullen   Last Updated November 16, 2018 21:01 PM

When using a UWP app (ie: OneNote, Todoist), I have an issue where the screen will render fine to the loaded size, but if I resize the window it doesn't want to extend beyond the original size.

For example, if I open a program and the window opens to 1/4 the screen size and I hit maximize, the window controls will maximize to the full window (I can click where the close button should be and it'll work, just the close button won't be visible), but the visible UI will only fill the original 1/4 area. I can move this around and it'll move to different parts of the screen, but the visible window will still be the original size.

Here is a screenshot:

Questions : Is your monitor very high-resolution and is set to much more than 100% ? Does the problem go away if you reboot? Are you on Windows 10 v1803?

Some suggestions:

  • If you resize the window, then close and reopen the application, it might then be the right size.
  • Run Performance Options (SystemPropertiesPerformance.exe) and uncheck Show window contents while dragging, then reboot:
