[BUG](Linux) Wrong scale in HiDPI screen and text Location report to input method

New Contributor

 

Hello, I am using Arch Linux with:

OS: Arch Linux x86_64

Kernel: 5.11.16-arch1-1

Shell: zsh 5.8  
Resolution: 3840x2160  
DE: Plasma 5.21.4  
WM: KWin

microsoft-edge-dev: 91.0.864.1

 

I am using a 4K monitor, so I set the system scale to 200%, and it works well in most applications. However, edge presents a vary big interface, about 2 times larger than normal. I tried "export GDK_SCALE=1", than lunch microsoft-edge-dev in the terminal, the interface become normal, but when I lunch download file in edge, the file manager (dolphin) become 0.5 smaller than normal. 

 

What's more, edge seems incompatible with input method (Fcitx), the location where float bar should be present in the left up of the position. Chromium fixed the issue (Refers to: https://bugs.chromium.org/p/chromium/issues/detail?id=475718 ).

 

I tried Google Chrome, and it works prefect without the two bugs. Both of the two are my favorite browsers, wish it can be fixed. Thanks a lot!

 

Here is my output of env :

Solution
Hi,
I had this scaling issue today after installing Edge beta on Kubuntu (KDE) and we found a solution from here: https://wiki.archlinux.org/title/HiDPI#Chromium_/_Google_Chrome

Launch Edge with the following flags: --high-dpi-support=1 --force-device-scale-factor=2
To make these changes permanent, copy the .desktop file from /usr/share/applications to ~/.local/share/applications and add the flags to "Exec" before the "%U" in the file.

This will override's Edge's scaling and forces an absolute scale of 2 (1 = 100%, 2 = 200%).

Hope this helps!
It works!
Sadly, this bug have not been fixed by Microsoft officially yet.
