@Michal_Mlejnek: How did you enable scaling in your desktop? Did you change the scale value in the Display settings: http://i.stack.imgur.com/rK9ep.png? What is the value in your case?
@EWal: Scaling is only supported on GNOME based desktop environments currently, apologies. The org.gnome.desktop.interface scaling-factor value in gsettings is the one used by GNOME, so it’s not a new scaling setting.
Yes I enabled the scaling and in my case its 1.5
I also have the same problem. The scaling-factor for me is 2. But insync does not seems to honor it

@Michal_Mlejnek: I see. Currently Insync only scales in whole number steps (x2, x3, etc.). Since your scaling value is 1.5 it’s rounded down to 1. This will be changed in a future release.
@Valerio_Mariani: What Linux distribution and version are you using, and what desktop environment?
I tried with: Unity on Ubuntu 16.04 and Gnome 3.18 on Fedora 23
Thanks for looking into this
I’m also hitting this issue with the Cinnamon desktop environment, Most other applications just work - I didn’t have to change any settings either in Cinnamon or my applications. But insync is tiny 
What toolkit is Insync written with? e.g. QT5? https://wiki.archlinux.org/index.php/HiDPI#GUI_toolkits
@Tom_Denham: Insync uses PySide and Qt 4. HiDPI is currently supported in Unity and GNOME. Please try running the following commands to check if Cinnamon can also be supported:
gsettings get org.gnome.desktop.interface scaling-factor
gsettings get org.gnome.desktop.interface text-scaling-factor
gsettings get org.gnome.settings-daemon.plugins.xsettings Gdk/WindowScalingFactor
This is still not fixed (3 years later). What can we do? I run gnome and all apps look good except for insync. The output of gsettings get org.gnome.desktop.interface scaling-factor in my case is uint32 0 which means “automatic scaling”. You should use something like gdk_screen_get_monitor_scale_factor to get the actual factor and not rely on that property.
+1 for HiDPI support. InSync is the only app on Gnome that doesn’t scale properly. I won’t hold my breath, as it appears this issue has been noted for many years, but wanted to add another request.
+1 for HiDPI support. Any news here ?
+1 for HiDPI support (a couple months later). This is still not properly working.
+1 for HiDPI support - using DELL XPS 13 with 3200 x 1800 screen - pretty much unusable
@cbernard333 @falconapps Hey guys, what’s your OS version?
Rest assured the HiDPI fix will be released soon so we can put this to rest. 
Ubuntu 18.0.1 (standard Ubuntu)
Just add variables QT_AUTO_SCREEN_SCALE_FACTOR=1 QT_SCREEN_SCALE_FACTORS=0.5 to /usr/bin/insync and /usr/bin/insync-headless:
#!/bin/bash
cd /usr/lib/insync
LC_TIME=C QT_AUTO_SCREEN_SCALE_FACTOR=1 QT_SCREEN_SCALE_FACTORS=0.5 exec ./insync “$@”
Now it looks normal.
any news about this features?
HiDPI support is in the works 
thanks, this actually fixes it!
