            Bug ID: 42462
           Summary: Severe hang in several places in FFXIV
           Product: Wine-staging
           Version: 2.1
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: spryor at redhat.com

After playing FFXIV for a certain amount of time, or in certain locations (I
haven't noticed a common shader that seems to trigger this) the game will
experience a severe hang. When running perf top to examine what's going on,
this line stands out:

Overhead  Shared Object                       Symbol
   9.22%  wined3d-csmt.dll.so            [.] 0x0000000000048362

It seems to vary from around 7-15% when not experiencing the issue, to around
50%. The jump in overhead accompanies an almost total lockup of the desktop, if
the game manages to recover, it usually accompanies graphical glitches not
present before the lockup, and will usually crash not too long after recovery
if gameplay proceeds (which I would hazard a guess is due to framebuffer
corruption)

Variant: Fedora 25, fully updated as of 2/16/2017
Desktop: KDE
Processor: i7-7700k
GPU: Nvidia GTX 1080 (with proprietary driver 378.13)
WINE: wine-2.1-1.fc25.x86_64 (current from the fedora repos as of 2/16/2017)
