Bug ID: 420294
Summary: Chrome drops Qt scaling environment variables
Product: plasma-browser-integration
Version: unspecified
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Chrome
Assignee: k...@privat.broulik.de
Reporter: audv...@gmail.com
Target Milestone: ---
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.
