As I’ve not been able to reproduce this issue myself, I’m wondering if it’s possible to keep your optimal DPI setting (of 100) and tweak one of Komodo’s file’s to suit.
The file is scimoz_wrapper.js inside of your Komodo installation, full location is: Komodo-IDE-9/lib/mozilla/components/scimoz_wrapper.js
And then find the number 96 (see below) and change it to your wanted DPI value:
I ran into this issue (right mouse click de-selection) in Mint 17.3 (distro based on Ubuntu), it’s extremely frustrating so I wanted to post my experience. To resolve, go to System Settings, Fonts, Font Settings pane, reduce the Text scaling factor to 1.0. Best of luck with this fantastic IDE.
I am using Komodo Edit 11.1.2 and I am still experiencing this exact same issue. The platform is Ubuntu and display scaling is 200%. When I run xdpyinfo | grep dots it returns “resolution: 96x96 dots per inch”. Any ideas what is causing this? This is the only application I have experienced this behavior in.
