Bug ID: 1500412 Summary: Eclipse + Wayland + HiDPI = huge icons Product: Fedora Version: 27 Component: eclipse Assignee: akurtako@redhat.com Reporter: rderooy@lenovo.com QA Contact: extras-qa@fedoraproject.org CC: akurtako@redhat.com, andjrobins@gmail.com, dbhole@redhat.com, ebaron@fedoraproject.org, eclipse-sig@lists.fedoraproject.org, jerboaa@gmail.com, jjohnstn@redhat.com, krzysztof.daniel@gmail.com, lef@fedoraproject.org, mat.booth@redhat.com, rgrunber@redhat.com
Created attachment 1336784 --> https://bugzilla.redhat.com/attachment.cgi?id=1336784&action=edit Eclipse screenshot with large icons
Description of problem: When running Eclipse on Wayland on a HiDPI display, icons in title bars and menus get super sized which causes very little space to be available for other things.
This also happens in any drop down lists with icons in them, causing them not to fit on the display.
What seems to happen is that instead of the icons getting double scaled, they are getting scaled up twice to a 4x scaling.
This does not happen when running the same version of Eclipse on X11, it also does not happen with any other applications on Wayland
Version-Release number of selected component (if applicable): eclipse-platform-4.7.1-6.fc27.x86_64 gtk3-3.22.24-1.fc27.x86_64 xorg-x11-server-Xwayland-1.19.3-8.fc27.x86_64
How reproducible: every time
Steps to Reproduce: 1. HiDPI / UHD / 4K display 2. Wayland 3. start eclipse
Actual results: Huge icons
Expected results: icons scaled to 2x
Additional info: If before starting Eclipse, I change the gnome display settings to 100x instead of the 200x scaling and then start Eclipse the icons are sized properly compared to the rest of the elements. Only issue is that everything is then very small and hard to read. If I change the setting while Eclipse is running I get strange results.
