High DPI Screen Support

When running RapidMiner Studio with high DPI screens you might run into scaling issues due to limited high DPI support in the current Java Runtime Environment implementations (JRE 8) on some platforms, in particular Windows and Linux. Unfortunately, we have little to no control over this particular issue, so you will have to resort to one of the workarounds listed below in the meantime.

OS X

OS X offers full High DPI (Retina) Screen support from OS X 10.7 version and onwards.

Windows 10

To solve scaling issues it is possible to use the scaling behavior switch that Windows 10 offers for individual apps since the Creators Update.

Note that you need the Creators Update for Windows 10 to make use of this feature. It will simply not be there if you do not have the update. To check if it is installed, you can use the command winver in the command line and check the version number of Windows. It must be at least version 1703.

To use the Creators Update feature to fix the scaling, follow the steps below:

  1. Navigate to your installation folder of RapidMiner Studio and locate the RapidMiner Studio.exe file.
  2. Right-click the file and select Properties.
  3. Go to the Compatibility tab.
  4. Select the checkbox Override high DPI scaling behavior
  5. Choose System.
  6. Press the OK button at the bottom.
  7. Run RapidMiner Studio via the RapidMiner Studio.exe again. It should now be displayed with a scaling that fits your high DPI resolution.

We strongly encourage getting the Creators Update for Windows 10 because the following way has undesirable side effects!

To solve scaling issues if you do not yet have access to the Creators Update, you can do the following:

  1. From the Windows Start Menu select Settings then System.
  2. There, locate the Display settings and adjust the scale so RapidMiner Studio is properly displayed.

Windows 7 and 8.x

Running RapidMiner Studio on Windows 7 or Windows 8.x with a high DPI screen will exhibit scaling problems due to the JRE 8 limitation mentioned earlier. Unfortunately the built-in scaling adjustment does not solve the issue directly, so another workaround is needed prior to scale adjustment; namely to edit the manifest entries of the java.exe and javaw.exe that come bundled with RapidMiner Studio.

To do this follow the steps below:

  1. Download a resource editing tool (for example ResourceHacker is a good candidate)
  2. Assuming that the installation folder of RapidMiner Studio is $RAPIDMINER_HOME, locate the java.exe and javaw.exe files under the $RAPIDMINER_HOME\jre\bin folder.
  3. Make sure to backup the java.exe and javaw.exe file before you proceed.
  4. Edit the java.exe and javaw.exe files with the resource editor you downloaded during the first step. In case you do not have sufficient rights to edit the files, run the resource editor as as an administrator.
  5. Locate the Manifest entry and select the 1.0 entry under it. Edit the XML by setting the dpiAware element to false: <dpiAware>false</dpiAware>
  6. Save the file. Some resource editors will have an option to compile the edited files for the changes to take effect. In that case you should also compile the file.
  7. Finally you will need to adjust the scaling via your display settings. Go to Control Panel > Appearance and Personalization > Display and change the scaling settings.
  8. Run RapidMiner Studio. It should now be displayed with a scaling that fits your high DPI resolution.

In Windows 7 platforms there are two prerequisites for the scaling adjustment to take effect:

  • You are using an Aero Theme. To check which theme you are currently using, go to Control Panel > Appearance and Personalization > Personalization and make sure to choose a theme under the Aero Themes section.
  • You are not using Windows XP DPI scaling. To make sure this is the case, please go to Control Panel > Appearance and Personalization > Display > Set custom text size(DPI) and make sure that Use Windows XP Style DPI scaling is not checked.

Linux Distributions

While some of the more common desktop environments in Linux distributions offer scaling adjustment features, these are only applicable for GTK+ 3 based application software. Current JRE implementations are using the underlying XLib library instead and as a result do not benefit from any scaling adjustment.

To work around this problem, please pass the following parameter when launching Studio: -Dsun.java2d.uiScale=2 and adapt the scaling factor as needed for your setup.
