1. [NOT APPLICABLE TO 1.1.3 and above] Upon first launch the Settings "Visual" tab had preselected a rather weird resolution for my screen (1918x1030), which additionally is not available in the dropdown choices. (My display allows up to 1920x1080 which is the Desktop resolution I use). Update: This is not the case in version 1.1.3. Tested with Ubuntu 14.04.2 LTS, Ubuntu 14.10 and SteamOS build 153. The bug was either fixed at some point, or it is an issue with LinuxMint 17.x OS, which does seem to have a few issues determining full screen dimensions for some games.
2. [PERSISTS IN 2.0.0] On many scenes (starting from the first playable one next to Zoe's bed, there appear black lines where light rays should be (this could be a similar bug as the reported about black boxes, although I don't get black boxes anywhere with the proprietary drivers, and what I get is different from what I have seen in those screenshots). This occurs no matter what the Visual settings are set to. I tried everything on Low, Medium/Custom and everything on AWESOME/HIGH settings and the problem persists for all of those. Update: The bug persists in 2.0.0. Tested on Ubuntu 14.04.2 LTS, Ubuntu 14.10 (for 1.1.3 version) and SteamOS build 153 (version 1.1.3 and 2.0.0). Probable reason is that some shaders are unsupported by a combo of drivers and OS.
3. [KNOWN ISSUE] On the starting cutscene at the overview with the burning boat, the fog glitches out and as a result part of the background scenery flashes on and off (as if the fog switches between full thick and not so thick). A video would be more appropriate to showcase this, but I haven't got a recording yet (I will as soon as I figure out how to do this on Linux). The two screenshots were taken in direct sequence and should somewhat indicate the issue. Again no difference if settings are low, medium or high (including enabling/disabling depth of field and lowering shadow draw distance). Update: Some fog volumes were disabled for the Linux version.
4. [NOT APPLICABLE TO 1.1.3 and above] In addition - this is probably a Steam issue but I'm reporting here because you never know- the Linux version did not recover my saves (from the Windows version) from the Cloud. Meaning, either that Steam does not allow this (using the same saves from the Cloud storage across operating systems for the same account) or that for some reason this process failed for me / for this game. I actually don't know. Update: Upon first launch of the game via Steam, it will probably won't sync with the Cloud. But if you quit and re-launch it, it will sync your saves with the Cloud (across Operating Systems). Tested on Ubuntu 14.04.2 LTS and Ubuntu 14.10. Also tested on SteamOS build 153 with the same results (syncing is achieved only after second launch of the game)
5. [NOT A BUG FOR LINUX] On a positive note, in comparison to the Windows version, on the same system, the laser eyes bug does not occur for any character -so far- in the Linux version, no matter the settings used (tried with everything on AWESOME/HIGH (even SSAO) and it still is not there). Update: The laser eyes bug in the Windows version has been fixed for some configurations - it's not completely fixed but it's certainly less frequent/intense.
6. [PERSISTS IN 2.0.0] The game settings in the Linux version get reset everytime you restart the game. The culprit file named "prefs" should be created (for linux) under the path "~/.config/unity3d/Red Thread Games/Dreamfall Chapters/" in my home folder, but it does not even when I change the settings and press "Apply Changes", quit the game and restart. The only workaround that works is to forcefully close the game's window (quickest way would be to ALT+F4 exit out of the game). The advice in the FAQ is to change the permissions of the ".config" folder to 777 (all granted) but this is both ill advised, and is not guaranteed to work, since the ".config" is already under my home folder and I am set as the owner of it and it's contents. This bug is also mentioned here with the workaround, also here (with the workaround) and here (with the advise to set the owner, but the folder was already owned by my user account and here on the steam forums. Tested on Ubuntu 14.04.2 LTS and Ubuntu 14.10 (up to 1.1.3). Also tested on SteamOS build 153, where this bug is present. Update for 2.0.0 version: The workaround does not seem to be working at all now in Linux.
7. [KNOWN ISSUE] PS3 controller support may need some extra work from the user to work fully. dc740 has provided a detailed guide on how to get USB connected and wireless PS3 controllers to work with the game (look here and here for a dedicated thread)
CPU: Old: AMD Phenom II x4 955 BE @3.2GHz. New: Intel Core i7 5930K @3.50GHz
RAM: Old: 14 GB DDR3. New: 8 GB DDR4.
GPU: ASUS HD7950-DC2T-3GD5-V2, Catalyst 14.9 drivers [for 1.1.1 testing] and Catalyst 14.12 OMEGA [for 1.1.3 testing] (for Linux I also use the AMD proprietary drivers*)
OS: Windows 7 Ultimate x64 SP1 / Linux Mint 17 x64 [for 1.1.1 testing] / Linux Ubuntu 14.10 and 14.04.2 x64 [for 1.1.3 testing] (all updates installed)
HDD: Steam installation of Dreamfall Chapters on a OCZ Vertex 4 SSD drive (windows) and on an HDD SATA2 drive for Linux.
*. The open source drivers are horrible (still in 1.1.3) for Dreamfall Chapters (Steam already complains about them when launching the client itself). Dreamfall Chapters runs with the image covered in numerous black boxes and only a small part of it shown to the player (it is unplayable). And in addition it also has the black rays artifacts issue that the proprietary fgrlx drivers have. The fgrlx drivers that you can install via the Linux "Driver manager" are similar in performance (if not a bit slower) with the 14.9 or the 14.12 drivers that I downloaded directly from AMD's site.
