The launcher is laggy or freezes for a period of time.

NOTE: This mod is not included in Freth's Modpak. You will need to install it manually. If you need help installing the mod, see the procedure here for manual installation. Links below for download.

This mod fixes a nine year old bug that (may) occur on Windows systems with multiple displays at varying resolutions and refresh rates. It manifests itself by more or less freezing your OS for 5-20 seconds when you start up Wurm Unlimited.

In addition to the bugfix it also adds:

• One-click login to a server (circumventing launcher) (great for alts!)
• Remove “do you want to quit?” warning
• Show IP in server browser (for when you want to create one-click logins)

This is an excerpt from the Steam Forums:

• Edit your LaunchConfig.ini file (both client and server has one after being started once)
• Add the following line under [VMParams]: JvmParam2=-Dglass.accessible.force=false

NOTE: JwParams are indexed so you have to add an index number appropriate to the JvmParam options you already have; sequential with the next number. Replace 2 with the appropriate next number.

Also, Xype has had good luck with these LaunchConfig.ini settings.

“Have a look at your keybindings.txt file for excessive duplications.”

“I used to have to sit and wait forever to get the launcher to open when I had a similar issue. It was a bug with keybindings.txt growing to a monstrous size by spamming duplicate lines, and going from like 3 kilobytes up to 20 megabytes or more.”
