Hi, sorry for necrobumping, but I just installed ROOT on my new Lenovo Carbon X1 and have the same exact issue. It is well known that HiDPI support in Linux is still quite poor, but I managed to fix most of problems with GUI apps by increasing Xorg’s dpi
setting as described e.g. here.
I wanted to know if there are any news about this issue. As most modern apps do, ROOT should respect the Xft.dpi
setting.
