Hi, This issue may be occurring due to the scaling behavior Java is performing for high-resolution displays. Can you please try the following? - Adding "-Dsun.java2d.uiScale=1" to your _JAVA_OPTIONS variable globally - If the above does not work, you can try editing the java.exe in the installation directory to override the scaling behavior: https://pivotce.com/2017/12/11/fix-java-applications-for-high-dpi-display/ Which version of Java are you using? How are you launching Burp?

Thanks for that information. You should ideally be using the Java version included with the installer (OpenJDK 14+36-1461). Try using the platform installer (.exe) or the appropriate java version on the JAR. Also, if you are launching via the command line, you may find the information below helpful: - https://portswigger.net/support/using-burp-suites-command-line-arguments - https://portswigger.net/support/launching-burp-suite-from-the-command-line

Hi I had a similar issue of Burp Pro (v2020.9.1) looking blurry on Windows 10. I tried the various suggestions without any success. The only thing I got working was to run this instead: "C:\Program Files\Common Files\Oracle\Java\javapath\java" -Dsun.java2d.uiScale=1 -jar "C:\Program Files\BurpSuitePro\burpsuite_pro.jar" I had added -Dsun.java2d.uiScale=1 to _JAVA_OPTIONS as suggested above, but that didn't work so I'm not sure why it works doing this. Although this stops everything looking blurry, it does output the following followed by lots of other output: Your JRE appears to be version 15 from Oracle Corporation Burp has not been fully tested on this platform and you may experience problems. WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by burp.c5t (file:/C:/Program%20Files/BurpSuitePro/burpsuite_pro.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int) WARNING: Please consider reporting this to the maintainers of burp.c5t WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release BurpBountyGui line 1882:C:\Program Files\Common Files\Oracle\Java\javapath\tags.txt (The system cannot find the file specified) BurpBountyGui line 1882:C:\Program Files\Common Files\Oracle\Java\javapath\tags.txt (The system cannot find the file specified) I don't know how else to make it look clear, but I don't know if this method will just cause me lots of problems?

Adding -Dsun.java2d.uiScale=1 to the BurpSuiteCommunity.vmoptions file in installation directory worked for me!

I had to enable "Override high DPI scaling behavior" and set it to "Application" for the "Burp Suite Professional" task like this: https://www.netphantom.com/info/Java-DPI-aware/index.html I also had to add -Dsun.java2d.uiScale=2 to the BurpSuiteCommunity.vmoptions because of the high res display.
