VLC UI scaling broken on Lubuntu 18.04

[user1230948457]

Using

Code: Select all

apt install vlc

(i.e. the VLC in the Ubuntu repository, 3.0.2), I get the following interface:



The controls are way too big for the DPI of the screen. So are the menus and dialog boxes.

Any ideas on how to fix this? I have a pretty average 23" 1920x1080 screen. No other Qt applications seem to have this problem.

Thanks for the link to the thread. I figured it out and posted a solution there.

I had to add

Code: Select all

QT_AUTO_SCREEN_SCALE_FACTOR=0

to my /etc/environment file.
