Do you still experience the issue with SWT 4.10? What about on Ubuntu 18.04? Also the snippet attached uses Java FX, is it reproducible with a regular SWT Canvas?
Wanted to look how does SWT perform under GNOME 3.30 with fractional scaling. For this I've downloaded swt-4.10-gtk-linux-x86_64.zip and org.eclipse.sdk.examples.source-4.10.zip, unpacked these and launched java -classpath swt.jar:plugins/org.eclipse.swt.examples_3.106.300.v20181018-1329.jar org.eclipse.swt.examples.controlexample.ControlExample Looks very nice (except for double-wide square border in canvas example), but it just asked me to fill a bug like this one. :) My environment: Arch Linux gnome-shell 3.30.2 gtk3 3.24.5 webkit2gtk 2.22.5 (swt version: 4922r32) SWT Glue code version: 54.0 info: +BrowserFunction/GDBus, +WebkitExtension Folder versioning, +WebKitExtension OSGI support, +setUrl(..postData..), -setCookie(), -getCookie +mouseDown/Focus Stacktrace is almost the same, just line numbers are different: java.lang.Throwable: at org.eclipse.swt.browser.WebKit.getStackTrace(WebKit.java:489) at org.eclipse.swt.browser.WebKit.getInternalErrorMsg(WebKit.java:482) at org.eclipse.swt.browser.WebKit.access$200(WebKit.java:124) at org.eclipse.swt.browser.WebKit$Webkit2Extension.initializeWebExtensions_callback(WebKit.java:594) at org.eclipse.swt.internal.webkit.WebKitGTK._webkit_web_view_new(Native Method) at org.eclipse.swt.internal.webkit.WebKitGTK.webkit_web_view_new(WebKitGTK.java:1928) at org.eclipse.swt.browser.WebKit.create(WebKit.java:1142) at org.eclipse.swt.browser.Browser.<init>(Browser.java:102) at org.eclipse.swt.examples.controlexample.BrowserTab.createExampleWidgets(BrowserTab.java:98) at org.eclipse.swt.examples.controlexample.Tab.createTabFolderPage(Tab.java:1264) at org.eclipse.swt.examples.controlexample.BrowserTab.createTabFolderPage(BrowserTab.java:179) at org.eclipse.swt.examples.controlexample.ControlExample.<init>(ControlExample.java:71) at org.eclipse.swt.examples.controlexample.ControlExample.main(ControlExample.java:225)
Forgot about JDK: Exactly the same under OpenJDK Runtime Environment (build 11.0.2+7) and OpenJDK Runtime Environment (build 1.8.0_202-b26).

How are you running ControlExample in this case? Do you have the SWT binaries set up and linked properly?
I've downloaded swt-4.10-gtk-linux-x86_64.zip and org.eclipse.sdk.examples.source-4.10.zip, unpacked these and launched java -classpath swt.jar:plugins/org.eclipse.swt.examples_3.106.300.v20181018-1329.jar org.eclipse.swt.examples.controlexample.ControlExample No specific environment variables. I've unpacked native libraries from swt.jar and checked them with ldd. All references are resolved except for libjawt.so. Strange thing is that no library doesn't want libwebkit2gtk.

The name should be libswt-webkit2extension-gtk-4*.so.
No, this library is not present in the swt.jar I've downloaded.
