Warzone 2100 freezes repeatedly in full screen mode

[Felix Oxley]

Set Warzone to use full screen mode and 2560x1440 then restart.

Launch Warzone, choose Single Player > Start Skirmish Game

Whilst you are choosing game preferences or when you click the checkbox to begin the game the program will freeze. The issue came sometimes by overcome by switching to a different VT and then switching back.

I have been playing Warzone on Ubuntu for years using all versions up to the upstream 3.2.2 without any problems. This problem started with Ubuntu 16.10

I have replicated this problem on a clean download of Ubuntu 16.10 using the 3.1.1 version of Warzone from the software repository.

My system is Ubuntu Gnome 16.10 x64, Intel Skylake i5-6600K, HD Graphics 530

Further testing shows that this problem only occurs on 16.10 with the following settings:

   Active Sync is enabled (the default setting)
   Resolution 2560x1440
   Full screen

The problem does not occur in 16.04

Hi,

FYI, this problem is still present in Warzone 3.2.2 (built from source)

[Felix Oxley (felix-oxley)]

The Warzone devs respond as follows:

   http://developer.wz2100.net/ticket/4540

   Pretty sure this isn't our issue per se.
   We use SDL 2, so, that issue you are having is actually either SDL 2, or video driver, or gdm issue.
   Nothing we can do in our codebase to fix that, sorry.
   Closing as external.

I have tested on Ubuntu Gnome 16.10 with the latest upstream kernel 4.9.0.
This problem stills occurs.

[Felix Oxley (felix-oxley)]

I have tested Kubuntu 16.10 and the issue does NOT occur.

Summary:

Affected versions: Ubuntu 16.10, Ubuntu Gnome 16.10, Ubuntu Gnome 16.10 with Kernel 4.9, Ubuntu 17.04
Unaffected versions: Ubuntu 16.04 (all versions), Kubuntu 16.10

Since this bug affects Unity and Gnome sessions but not KDE sessions it is not a fault in Warzone itself.
Therefore I am changing the classification of the issue to Unity.

[Daniel van Vugt (vanvugt)]

Gnome sessions don't use Unity8. So the bug should not be assigned to Unity.

This is an unsupported release now. Please think to install the next LTS 'Bionic 18.04'
