No slide boders in slide sorter view

See the two attached jpg images. Both are for the exact same presentation, in the exact same version of LibreOffice, on the exact same version of Fedora (27). The slides with borders in slide sorter view is on a desktop with lower resolution screen. The slides with no borders are on a hiDPI laptop.

There is no configuration that I could find or Google for that allows setting of this border.

Ignore the blurry images in some of the slides themselves. That is a separate issue that I've already submitted bug reports about.

This has something to do with the gtk settings. I can eliminate the issue by setting

GDK_SCALE=2
GDK_DPI_SCALE=0.5

and starting ooimpress from the command line.

More notes for those noticing the same issue.

Setting the environment variables above isn't the greatest fix. Although the borders appear in the slide sorter view and panel, the resolution of the whole LO interface is blurred, including the slides and thumbnails. I don't know how to get around this, but it has to do with the chosen screen resolution and scaling factor of the hiDPI display. Perhaps there is some combination that can scale up the application but not be blurry? I tried many but couldn't find one. I'm using KDE and these settings are all configurable. In Gnome, all of this is set for the user and the LO interface is blurry from the start (at least on my laptop running Fedora 27).

Confirmed with a HiDPI display & Manjaro Linux

Version: 6.0.2.1.0+
Build ID: 6.0.2-1
CPU threads: 4; OS: Linux 4.14; UI render: default; VCL: kde4;

Problem still exists with KDE plasma 5 on Fedora 28, and LO 6.0.3.2. 

The key issue: setting the "force fonts dpi" to anything above 120 will result in LO impress not drawing the box around slides in slide sorter view. Setting GDK_SCALE or GDK_DPI_SCALE to anything one wants has no effect.

Bug is still present in 6.2.3.2. It is a hiDPI issue and is not present at low or lower resolutions.
