international character selection offset on high-dpi screen

onboard (Ubuntu)

Bug Description

When using a user-interface scaling > 1 (Ubuntu Control Center → Display), the sensitive areas of the international character selection popover is offset. It seems UI units and device units are confused. When you want to choose an international character, you have to touch the screen at twice the distance from the popover's top left corner.

Ubuntu 14.10
onboard 1.1.0~1908-0ppa1~utopic (from onboard snapshots ppa)
org.gnome.desktop.interface.scaling-factor = 2
screen resolution: 3200×1800px

Thanks for the bug report. I can't reproduce it in Vivid, but will try in Utopic later. 1.1.0~1908-0ppa1~utopic is slightly outdated too by now. We should get you an updated snapshot just in case.

Thanks! I tested the same procedure with 1.1.0+1944-0ppa1~utopic as described above and got the same observation.

Found it, the scaling was applied twice. Looking at your screen-shots there was another issue with keys getting stuck on the main keyboard. This shouldn't happen anymore either. Try it please and let me know how it goes.

Francesco, another snapshot please. Thanks in advance.

Revision 1949 of trunk containing the fix will be available in our Snapshots PPA for utopic and vivid as soon as launchpad has finished building them. Trusty and precise will follow later this evening.

Confirmed, 1.1.0+1949-0ppa1~utopic fixes the issue perfectly!
Thanks (again) for your very fast response. (From other projects I'm rather used to a response no earlier than a month and a fix after min. half a year.)

Thanks for the confirmation that your bug is fixed.

By the way, Onboard 1.1.1 has just been released containing among others this fix.



PS: I fully agree: Marmuta is doing an outstanding job with Onboard since quite some time, which is really great from his part.
