Q: Why is the Defold editor super small when run on a 4k or HiDPI monitor when using GNOME?

: A: Change the scaling factor before running Defold. [source](https://unix.stackexchange.com/a/552411)

  ```
  $ gsettings set org.gnome.desktop.interface scaling-factor 2
  ```


Q: Why does mouse clicks on Elementary OS go through the editor onto whatever is below?

: A: Start the editor like this:

  ```
  $ GTK_CSD=0 ./Defold
  ```


Q: Why does the Defold editor crash when I try to create a new project, or open an existing one?

: A: On certain distributions (like Ubuntu 18) there is an issue with the version of jogamp/jogl Defold uses vs. the version of Mesa on the system.

  See the following reports for more information:

  - https://github.com/defold/editor2-issues/issues/1905
  - https://github.com/defold/editor2-issues/issues/1886

  If this is your problem try the following workaround:

  ```
  $ export MESA_GL_VERSION_OVERRIDE=3.1
  $ ./Defold
  ```


Q: Why doesn't my Defold game start when I try to run it on Linux?

: A: Check the console output in the editor. If you get the following message:

  ```
  dmengine: error while loading shared libraries: libopenal.so.1: cannot open shared object file: No such file or directory
  ```

  then you need to install *libopenal1*. The package name varies between distributions, and in some cases you might have to install the *openal* and *openal-dev* or *openal-devel* packages.
