UI elements too small on high-resolution display under Windows 10

[Spike]

I'm attempting to run Inkscape Inkscape 0.92.1 r15371 for 64-bit Windows 10 on a laptop which has a 15-inch display with a resolution of 3840 x 2160 pixels. There is also an HDMI-connected projector with a resolution of 1920 x 1080 pixels.

Windows 10's display properties has a slider which allows users to globally select a zoom setting for all operating system and user interface elements, such as desktop icons. On this system, the zoom setting is to 250%, which just about makes icons the same size they would be on a standard-definition monitor.

However, the Inkscape toolbars and palettes appear microscopic under this system. There does not appear to be any adherence to the global zoom preference, nor any way to manually configure the Inkscape UI to increase the size of icons, menus, or other UI elements.

I've attached a full-resolution screenshot of the desktop of this machine with the Inkscape program open, with some desktop icons visible for size comparison.

I did a very cursory search of your bug tickets for a duplicate and found none reporting this precise problem, but I apologize in advance if this is a duplicate.

Hi Karina. Thanks for the note. I'm running Windows 10 build 1607 so I don't have the Creator's update yet, and that Properties option is not yet available to me.

I've just downloaded the Inkscape-0.92.1.7z (32-bit) and extracted gtkrc from the location you specified, and copied it to the location where the 64-bit Inkscape had its own gtkrc file, and then launched Inkscape.

When launched with this file replaced, the application shows no indication of the icons or UI elements being any larger, runs for about 3 seconds, and then closes unceremoniously and with no crash logged (that I could find in the Windows event log tool). I then took the original gtkrc file and placed it back in the same location where it had been installed by the .exe installer, and Inkscape still closes itself about 3 seconds after launch, with no apparent crash log details.

So, Inkscape 64-bit appears to be nonfunctional at this point. I will uninstall the 64-bit version and use the 32-bit version instead.

The 32-bit version does display the icons/elements at their correct proportions. I will continue using the 32-bit version but it would be nice if the 64-bit version were updated to eliminate this problem (or, at the very least, if there was a note about this incompatibility added to the release notes for the 64-bit version).

Thank you for your help.

Also, this does appear to be a duplicate of bug 1698026 and should be merged with that ticket.

You’re welcome Spike.

For Windows versions prior to the 1703 (creators edition) I had to use a modified (dpiAware to false) external manifest for the Inkscape 64-bit version.

This change (along with the difference in gtkrc) is probably what broke it for highdpi systems:
