[🐛 Bug]: Microsoft Edge with High DPI Settings Fails to Load Pages with Selenium WebDriver

[CTsakurada]

Description

Environment Details

• Java: 21
• Selenium: selenium-java 4.33.0
• Microsoft Edge Driver: 136.0.3240.64
• OS: Windows 11
• Microsoft Edge High DPI Setting: ON (Source: System)

Issue Description

When Microsoft Edge's High DPI setting is turned ON, Selenium WebDriver launches the browser but fails to load any pages. However, when the High DPI setting is turned OFF, everything works normally. This issue doesn't occur with Google Chrome browser with High DPI settings enabled.

• When I run the jar file with High DPI settings disabled for Microsoft Edge, the browser launches and displays the page correctly.

• When I enable High DPI settings (System) for Microsoft Edge and run the same jar file, the browser launches but no page is displayed.

• Google Chrome works correctly even with High DPI settings enabled.

I have tried killing all Edge processes before running the test and have confirmed that the issue is specifically related to the High DPI settings.
I tested with multiple Selenium versions including older ones, but the same problem persists across all versions.

Question

1. Could this be a compatibility issue between Selenium and Microsoft Edge with High DPI settings enabled?
2. Is there a way to make Selenium work with Microsoft Edge when High DPI settings are ON?
3. Are there any specific EdgeOptions or command-line arguments that could resolve this issue?

Supplement

To configure High DPI settings for Microsoft Edge (or any other app), follow these steps:

Right-click the desktop shortcut for Microsoft Edge and select "Properties".
Go to the "Compatibility" tab.
Click on "Change high DPI settings".
In the window that appears:
Under "High DPI scaling override", check the box "Override high DPI scaling behavior."
For "Scaling performed by:", select "System" from the dropdown.

This helps resolve any blurriness or scaling issues on high-resolution displays.

Here is a screenshot of the settings in Japanese (for reference), but the steps above reflect the equivalent English version.

Reproducible Code

package selenium;

import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.edge.EdgeDriver;

public class EdgeDriverSample {

	public static void main(String[] args) throws Exception {
		
		System.setProperty("webdriver.edge.driver", "C:/tools/msedgedriver.exe");
		EdgeDriver driver = new EdgeDriver();

		try {
			driver.navigate().to("https://bing.com");
			System.out.println(System.getProperty("webdriver.edge.driver"));
			WebElement element = driver.findElement(By.id("sb_form_q"));
			element.sendKeys("WebDriver");
			element.submit();

			Thread.sleep(5000);
		} finally {
			driver.quit();
		}
	}
}

If it works in Chrome and not in Edge, most likely and issue with Edge and not Selenium.

Hi, @CTsakurada.
This issue has been determined to require fixes in MSEdgeDriver
or in the IE Mode in Edge.

You can see if the feature is passing in the Web Platform Tests.

If it is something new, please create an Issue with the MSEdgeDriver team.

Feel free to comment the issues that you raise back in this issue. Thank you.
