Here is a list of client issues that have known causes & solutions.
Can't Change Server (Java 7 Update 80)
Https handling in this version of Java seems to be broken. With this broken server switching can't work, also the top lists and news will be unable to load.
Solution:
It is recommended to use the most recent Java 8 this version doesn't seem to have the problem.
Alternately install the game client through the download option on our website or Steam. These versions still have their own slightly older Java 7 JRE.
Client Fails to Launch in Hardware (OpenGL Version 1.1)
On some PCs the OpenGL version seems to be 1.1 by default. Eldevin requires OpenGL 1.5 so the game will fail to launch with hardware rendering.
You can check your OpenGL version using a tool like GLview.
It is very unlikely in most cases that the OpenGL support is actually such a low version, this seems to come from a default graphics driver.
Solution:
Updating your graphics driver or installing one specifically from your graphics card vendor should fix this.
Linux Ubuntu/Mint Freezes Loading Realm
Occasionally players find the game freezes when loading into a realm after selecting a character. There are 2 possible causes for this, an audio deadlock (certain Open JDK Java 7 versions) or the system is struggling attempting to handle the first frame in hardware rendering.
Solution:
The audio deadlock is easier fix so try this first. The recommended solution is to install the Oracle Java 8 JRE. Here are Ubuntu/Mint oriented install process guides:

If the issue persists the game is likely struggling with hardware rendering. For the time being the only option is to switch to software rendering. To enable software rendering it is best to use the Diagnostics Tool "eldevindiag.jar" which can be found in the Eldevin directory. Choose “Change Graphics Settings” in the “Configuration” section. Choose “Software” from the “Renderer” drop down. Save the change before running Eldevin again.
There are a more issues known at current but exact causes remain unclear. We will continue to try to work on problems and add to the list as we find solutions.
These kinds of problems are generally hard to diagnose so the information players provide in bug reports or tickets can help a lot. Thank you to those who have helped identify and diagnose these issues.
