Fullscreen Resolution Scaling Issues

Hello,

We’re encountering an issue related to fullscreen resolution behavior.

When running the game in fullscreen mode and switching from a higher resolution (e.g., 1920x1080) to a lower one (e.g., 1280x720), the screen appears to resize instead of maintaining fullscreen. As a result, the viewport becomes blurry, and the display quality significantly degrades — we would expect it to retain fullscreen mode and adjust internal rendering resolution accordingly, rather than physically resizing the screen.

Additionally, after switching resolutions, we observe the following issues:

  • Blinking edges around the screen.
  • Mouse cursor misalignment, where the cursor appears at one location but interacts with a different part of the screen on click/hover.
  • When switching from a lower resolution to a higher one while in fullscreen mode, only the top-left portion of the viewport is displayed, as if it’s not correctly scaling to fit the screen.

We attempted to reproduce this in the Lyra Starter Game, and the same behavior occurs there. Please refer to the attached video for a demonstration of the issue.

Could you please advise if there’s a proper way to handle resolution changes in fullscreen mode, or if this is a known issue? Any guidance or workaround would be greatly appreciated.

Thank you,

Harut
