In the Oracle SQL Developer on my manjaro Linux, the blinking cursor in the editor area won't show anymore. I deleted everything of local config files (~/.sqldeveloper/) and reloads the program. At first, the cursor is visible again but after i pressed the "excute script (F5)"-Button, it will get lost and there seems no way to fix this.

My setup:

SQL Developer

Version Build MAIN-21.78


java version "1.8.0_112" Java(TM) SE Runtime Environment (build 1.8.0_112-b15) Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)


Linux 4.4.39-1-MANJARO

Adding AddVMOption -Dsun.java2d.opengl=true to ~/.sqldeveloper/<version>/product.conf fixed it for me.

Sometimes the cursor gets hidden because of different monitor resolutions. Try to change the font size by going to Tools > Preferences > Code Editor > Fonts.
