SUMMARY

This is related to https://bugs.kde.org/show_bug.cgi?id=415421

When I run a KDE application such as Ark via Chrome (by clicking on the file in the download manager), it shows up with the incorrect scale because it does not have the environment variables that would normally be set:

QT_AUTO_SCREEN_SCALE_FACTOR=0
QT_SCREEN_SCALE_FACTORS=DVI-I-0=1.5;DVI-I-1=1.5;HDMI-0=1.5;DP-0=1.5;DP-1=1.5;DP-2=1.5;DP-3=1.5;DP-4=1.5;DP-5=1.5;

Chrome/Chromium now runs with a minimum environment which causes applications to lose environment variables set by Plasma or in ~/.xprofile or similar. However since it seems to use xdg-open, I can edit the .desktop file for an app and add environment variables, but this is very inconvenient.

Even adding `export QT_AUTO_SCREEN_SCALE_FACTOR=0` to .xprofile (and logging in again) does not fix this.

STEPS TO REPRODUCE
1. Open Chrome, download a zip file.
2. Click on the file in the download bar or download manager to open it with Ark.

OBSERVED RESULT

Ark opens with incorrect scale.

EXPECTED RESULT

Ark should respect the QT_AUTO_SCREEN_SCALE_FACTOR and QT_SCREEN_SCALE_FACTORS values when opened from anywhere.
