Description Ancoron 2015-05-15 12:50:20 UTC

My current version of package plasma-workspace is 4:5.3.0-0ubuntu1~ubuntu1 from the Kubuntu backports PPA, but the exact same problem also appeared with the "official" version 5.2.2.

My case seems to be a little bit similar to the case described in bug #346718, but I am actually using the Oxygen font and the offset seems to be higher in my case.

For now, I can see three specific cases where the rendering is vertically unaligned:
1. Password field in SDDM greeter
2. krunner command/search input field
3. application launcher "sections" (Favorites, Applications, Computer, Places, Leave)




Reproducible: Always

Comment 3 Ancoron 2015-05-15 15:49:18 UTC

I should probably add some other information about my environment:

I am running a dual-head configuration using 2x 30" Dell 3007 WFP-HC, so 2x 2560x1600 side by side to a 5120x1600 virtual screen.

The configuration is done manually using the good old xorg.conf, mainly because one of the monitors is connected through an active DisplayPort-to-DVI adapter, which apparently forgets to forward EDID requests and data, which forces me to manually configure correct mode lines.

As a side effect, X does not seem to be able to make use of its officially documented way to influence DPI calculation using the "DisplaySize" property inside the xorg.conf.

Comment 7 Ancoron 2015-05-16 08:55:56 UTC

Correcting the DPI using an Xsession script corrected the scaling problem for the application launcher icons but did not change anything for the vertical alignment on input fields.

For the DPI, I've created a separate issue now: bug #347783

does this still happen?
