Fix Windows Font Scaling in Visere Captura. If you experience crashes, missing tool dialogs, incorrect font sizes, or strange window painting behavior when moving Visere Captura between a laptop screen and an external monitor, the issue is typically related to Windows DPI scaling.
1. Why This Happens
Visere Captura is built using a cross-platform user interface framework called Qt. On Windows systems with mixed-DPI displays (for example, a laptop screen at 150% scaling and an external monitor at 100%), certain versions of Qt can exhibit rendering and window-management issues.
These issues may be addressed in the future through updates to the underlying Qt library, but on current versions of Visere Captura, Windows DPI scaling above certain thresholds can cause instability.
2. Common Symptoms
- Visere Captura crashes when dragged between monitors
- Tool windows appear missing or off-screen
- Fonts appear too large, too small, or distorted
- UI elements fail to repaint correctly
3. DPI Scaling Limitation
To avoid these issues, Visere Captura should run at a maximum DPI scaling of less than 150%.
When Windows applies per-monitor scaling above this level, especially when moving the application between displays, Qt may not correctly recalculate font sizes and window positions.
4. Available Solutions
You have two possible ways to resolve the issue:
- Reduce the DPI scaling on the external monitor to a maximum of 125%.
- Override DPI scaling behavior for Visere Captura so Windows forces a consistent scaling mode regardless of monitor.
The second option is recommended if you prefer to keep higher DPI scaling for other applications.
5. Step-by-Step: Override DPI Scaling for Visere Captura
- Navigate to the Visere Captura installation directory.
Default path: Program Files\DMMD Inc\VisereCaptura - Right-click on Visere Captura and select Properties.
- Open the Compatibility tab and click Change high DPI settings.
- Check Use this setting to fix scaling problems for this program instead of the one in Settings.
- Check Override high DPI scaling behavior.
- Set Scaling performed by: to System.
- Click OK, then Apply.
- Restart Visere Captura.
Note: After applying this change, Visere Captura will always launch using system-level DPI scaling, which prevents crashes and UI inconsistencies when moving between monitors.
