Freecad .19 GUI Issues on Manjaro Linux [SOLVED]

[darbu12345]

Hi all,

I've been using FreeCAD for a long time, and I'm quite a fan!
This is my first post, so far I've never met an issue I can't resolve on my own, but the last few weeks have been quite frustrating.

Ever since I upgraded to a 4k monitor, the FreeCAD GUI has been putting up a fight. Usually, I used to run Freecad from the latest APP image, but icons and text there are too small, and the GUI is not cooperating with system-wide settings like general scaling and qt5 font size settings.

I was happy to see that FreeCAD was back on the supported packages of Manjaro again, and I decided to install it. The good news is that now the text size is responding to changes from qt5 settings, but all of the Icons and drop-down menus are messed up, misaligned, and constantly disappearing.

I did not find a similar issue on the forum.
I'm running with the latest Nvidia drivers available for my kernel.

My guess is that there is something wrong with my qt5 environment, but I have no idea what to do, what to check, in order to fix my issue :/.

This info is from the package installed from the Manjaro repos:

This is a HiDPI thing. Search for that in the forum.

Hi Kunda1,

Thank you for the speedy reply!
You are correct! Turns out the issue is with QT5 handling the high dpi scaling.

In order to fix the issue I added the following to my bashrc:

Code: Select all

#Disable qt auto-scale
export QT_AUTO_SCREEN_SCALE_FACTOR=0
#Set manual scaling factor
export QT_SCALE_FACTOR=1.5
