Sloppy Forgeries Mouse Movement Fix: Aspect Ratio Bug

Update the free demo to v.0.8.0 (released November 4, 2026) — that build contains the official mouse movement fix for widescreen aspect ratios. In the Demo Update v.0.8.0 notes on the official Steam page, the developer states: "Bug fix. Wide screen previously would distort mouse movement." So if your strokes feel stretched or inaccurate, the first action is simply updating the demo through Steam and restarting the game.

What the bug looked like

Before the patch, the game mapped mouse input to the window without correcting for the aspect ratio. A player on the Steam Community hub described the symptom on November 3: at 16:9 the mouse behaves correctly — draw a circle and a circle appears — but in portrait mode or on an ultrawide monitor, drawing a circle produces a stretched oval instead (tested on Windows 10 by the player). In a game that scores you pixel-by-pixel on accuracy, that distortion makes every stroke land in the wrong place.

The developer's patch note only names widescreen as fixed, so the extent to which v.0.8.0 also covers portrait and ultrawide ratios is not explicitly confirmed in the notes. If you play on an ultrawide or portrait display, test a circle stroke after updating and check whether the on-screen line matches your hand movement.

1. Open Steam and go to your Library

   Find Sloppy Forgeries under the demo section of your library.

2. Let Steam update the demo

   If v.0.8.0 is not already installed, Steam should download it. If it does not, right-click the demo, choose Properties, then check under Installed Files.

3. Restart the game and test a stroke

   Draw a slow circle on a canvas and confirm it appears as a circle rather than an oval.

Next steps

• If your strokes are fine but the pen itself is not detected, see the Wacom tablet support page — tablet input was added separately in July 2026.
• Before adjusting graphics settings to chase input problems, compare your setup against the system requirements page — the game requires an external mouse on Windows.

FAQ

What exactly caused the distorted mouse movement in Sloppy Forgeries?

The game did not correct mouse input for the window's aspect ratio, so strokes were stretched on non-16:9 screens. The developer fixed it in Demo Update v.0.8.0 with the note "Wide screen previously would distort mouse movement."

Do I need to change any settings to apply the mouse movement fix?

No. The fix is in the v.0.8.0 demo build itself, so updating the demo on Steam is all that is required. There is no in-game toggle mentioned for it.

Does the fix apply to the full game?

The full game is not out yet — as of November 9, 2026, the official Steam store page lists it as coming soon on November 13, 2026 for Windows. The fix shipped in the demo build, and whether the launch version inherits it is expected but not separately confirmed.

Checked November 9, 2026 against the official Steam store page with developer announcements and the Steam Community hub, including a first-hand player report of the pre-patch symptom. Whether v.0.8.0 fully corrects portrait and ultrawide (not just widescreen) remains unconfirmed.
