I've tried toggling drag_drop_simple_pidl on and off.
If I disable windows native preview handlers it will work fine.
How I disable:
Code: Select all
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"DisableThumbnails"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"DisableThumbnails"=dword:00000001
REG ADD "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /V IconsOnly /T REG_DWORD /D 1 /F
taskkill /f /im explorer.exe
start explorer.exe
(this is the Thumbnail Cache Out of Proc Server)
I've also attached a debug log where I triggered that behavior several times.
