           Summary: CLIP Studio Paint 4.10: Application performance issue
                    when selecting a material-based tool from the tool
                    panel
           Product: Wine
           Version: 10.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: -unknown

Terminal log showing the err:sync
CSP hangs for about one minute when starting a new session and selecting a
material-based tool, for example, a downloaded G-pen material, from the tool
panel. Selecting another similar tool will also cause the hang, but as long as
you do not switch tool groups, selecting the first material is instant.
There is also a lag when first attempting to use the tool on the canvas, and I
believe it is likely related, but I am happy to raise a new bug for that
behaviour.
CSP also hangs for longer when switching tool groups, if that tool group
contains at least one tool that uses a material.
From what I can gather, this might be related to a thread being locked by
another thread, but is then waiting 60 seconds to try again, as seen in lines
such as:
0158:err:sync:RtlpWaitForCriticalSection section 0000713087FB7238 "?" wait
timed out in thread 0158, blocked by 02b8, retrying (60 sec).
In the attached log is just the basic example of selecting a new material.
