[Bug 1316734] Re: Scaling factors for high DPI screens are sometimes applied twice

 

This issue is also reproduced in my 14.04 box.

In the unity-control-center I set scale factor to 1.5, before the issue
happen I checked some gsettings items:

gsettings get org.gnome.desktop.interface text-scaling-factor
1.5
gsettings get com.canonical.Unity.Interface text-scale-factor
1.0

then after several times reboot the issue is reproduced (I guess logout
and login will also trigger it), the effect is just like Martin's
screenshot. Now the two gsettings items are changed to:

gsettings get org.gnome.desktop.interface text-scaling-factor
2.25
gsettings get com.canonical.Unity.Interface text-scale-factor
1.5

I can manually restore it by below command, however the issue still will
be reproduced sooner or later.

gsettings reset com.canonical.Unity.Interface text-scale-factor

Title:
  Scaling factors for high DPI screens are sometimes applied twice

Status in Unity:
  New
Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  I have a high DPI screen, and thus configured Unity to scale
  everything by a factor of 1.62 (Under Settings -> Display). Sometimes
  after logging in the text is suddenly much larger than before, and
  this change persists even after reboot. I was able to get back normal
  font sizes by modifying text scaling in unity tweak.

  I'd have to look at this again the next time this happens, but if I
  understand this correctly then sometimes the scaling factor is re-
  applied to the text scaling in cases where it was already applied
  before, thus scaling the text by 1.62*1.62 instead of only 1.62 as it
  should be.
