Confirmed symptom and scope
In Rapid SCADA Webstation version 5.1.3.0, some views display horizontal and vertical scrollbars even though the view and monitor are both configured for 1920 × 1080. The browser zoom is 100%, and the fit-to-screen control is active. The issue was observed in Chrome, while the same views displayed normally in Firefox on the workstation tested.
| Condition | Observed result |
|---|---|
| Chrome opens an affected view | Horizontal and vertical scrollbars may appear, allowing the image to move. |
| Events panel is opened and collapsed | The scrollbars disappear and the view expands to fill the screen. |
| Firefox on the tested workstation | The affected behavior was not observed. |
Likely cause: modified plugin CSS
The scale-control panel appeared on the right side of the schematic. This indicates that the plugin CSS had been modified. Treat the custom CSS as the leading hypothesis, not a confirmed root cause: the available evidence does not identify the specific rule, selector, or dimension responsible for the overflow.
Opening and collapsing the Events panel likely forces the page to recalculate its layout, because that action removes the scrollbars. This explains the temporary recovery but does not prove which CSS declaration caused the initial sizing error.
Diagnostic and verification procedure
- Record the Webstation version and capture a readable screenshot showing the entire view, both scrollbars, and the scale-control panel position.
- Reproduce the view in Chrome with browser zoom at 100% and fit-to-screen enabled. Open and collapse the Events panel to confirm whether the layout returns to full-screen presentation.
- Open the same view in Firefox on the same workstation. Use the result only as a browser comparison; it does not by itself isolate the CSS rule.
- Test the schematic on a standard Rapid SCADA installation without the plugin CSS modifications. If the standard installation renders correctly, compare the customized CSS with the standard styling and remove or correct the change that introduces overflow.
- Verify the correction by switching repeatedly between views in Chrome and confirming that neither scrollbar returns without toggling the Events panel.
Separate infinite-loading symptom
An additional symptom was reported in which navigation between views could remain in an endless loading state. The evidence does not establish whether this behavior shares the scrollbar cause, and it provides no error message, network result, or confirmed remedy. Diagnose it separately by recording the affected view transition and collecting application-version details and readable screenshots before attributing it to the CSS customization.
FAQ
Why does Rapid SCADA Webstation show scrollbars at 1920 × 1080?
In the reported version 5.1.3.0 case, the view and monitor were both 1920 × 1080 with zoom at 100%. The right-side scale-control panel indicated modified plugin CSS, so test the schematic on a standard installation to determine whether that customization creates the overflow.
Why do the Rapid SCADA scrollbars disappear after toggling Events?
Opening and collapsing the Events panel removes the scrollbars in the reported case, consistent with a layout recalculation. Use this as a temporary recovery and diagnostic clue, not as the final correction.
How do I verify a Rapid SCADA Webstation scrollbar fix?
Test the same schematic in Chrome at 100% zoom with fit-to-screen active, then switch repeatedly between views. The fix is verified when the view fills the screen and both scrollbars remain absent without toggling the Events panel.
