Created attachment 282434 [details] Sample rcp app to reproduce the bug When adding a Tool Control with an internal text field to the Toolbar of a Window in an RCP application and running the application on 100% scaling on Windows, the content of the text field is correctly displayed. When running the application on, for example, a resolution 3840 x 2160 and a scaling of 225%, the text field is not resized accordingly to match the enlarged content. As a result, the content of the text field cannot be read by the user any more. For an reproduction, run the attached sample rcp app (which contains a single Tool control as describes above only) on Windows with the said resolution (or smaller) and a scaling of 225%.

Are only the fonts in the toolbar affected?? To me it seems that the scaling factor is ignored for *all* fonts.

Only text fields in toolbars are affected in our application; other fonts are scaled correctly. Is there any workaround until the issue is officially fixed? Any help would be appreciated. Best, MP
Besides, the text in text fields in toolbars of the RCP app gets correctly scaled when using the compatibility mode for the app's exe on Windows and switching the "High DPI scaling" to "System" (instead of of the default "application"). Is it possible to configure the RCP app programmatically accordingly?
One workaround is to manually apply the scaling to your Widgets in the ToolControl. I have not investigated any root cause, but the following snippet in the seems to correct the font. Label label = new Label(parent, SWT.NONE); label.setText("My Label"); FontDescriptor descriptor = FontDescriptor.createFrom(label.getFont()); int height = descriptor.getFontData()[0].getHeight(); int scaledHeight = DPIUtil.autoScaleUp(height); FontDescriptor scaledDescriptor = descriptor.setHeight(scaledHeight); Font scaledFont = scaledDescriptor.createFont(label.getDisplay()); label.setFont(scaledFont);

When including it in our application and logging the scaled height, the value seems to be correct. However, the size of the font is not the issue - also without the sample code included it gets computed correctly for the text field in the tool bar. The issue is with the size of the text field in the toolbar: its height does not get resized to match the height of the font, hence the content of the field is clipped vertically.
This could be a duplicate of Bug 465732, however, that does not depend on the scaling factor. Is the ToolControl the first item in the ToolBar? Or does it become the first one to be rendered on different scaling factors due to missing items, see referenced bugs?

However, as described in the initial bug report, we do encounter the issue in our RCP app on some scaling factors only.
Yet, the issue we see with the sample app that I have attached to this issue for reproduction seems to be the same as described in the #465732 indeed. So I'd be ok with the issue at hand being marked as a duplicate.
