Scaling issues with text in toolbar [message #1823993]

Hi,
We are currently seeing some issues in our RCP application where text and icons within a toolbar is nor properly scaled under windows. This happens on high DPI screens (4k) and zooming of 225%. Our application is run under such client environments that making them set the compatibility mode of the scaling to system as advised in https://superuser.com/questions/1230346/overriding-high-dpi-scaling-from-the-command-line/1230356 is not possible. Also we would like to not have to tell our users to do it manually.

My Question: is this a known or even fixed issue (we are using 4.12 to ship)? Is there a workaround?

Sorry if this has been discussed before, but I was unable to find satisfactory answers.

Thank you for your support.

Not sure what your scaling issue is related to, but the 'swt.autoScale' and 'swt.autoScale.method' options you could use to tweak the Eclipse scaling system, see https://www.eclipse.org/eclipse/news/4.6/platform.php#swt-autoscale-tweaks

thanks, we have used this to fix most of our issues, by setting swt.autoScale=integer and swt.autoScale.method=nearest . However there is still one scaling issue with text that appears in textboxes in toolbars. we can fix this issue by applying the fix described in the link i posted above, however we can not ask our users to change some OS specific application settings, nor will we be able to set registry keys on their machines.

I understand now. If the issue is only is in toolbars, and only on windows, it must be a bug. Could you create a bug report for Platform UI? If you have a minimal example showing the issue, please attach it to the bug report.
