Liquify face-aware filter requires GPU acceleration, but when I turn this on in Edit->Preferences->Performance I get an AIF internal execption error message. Interestingly, it works with Version 19.0, but not with the current version 19.1.2, so it can't be my hardware, right? (I haven't tried out every version in between to find out when it starts to break down). Is this a bug where we need to hope that this going to be fixed for next version?
I have not seen that problem here - but 19.1.2 is not the current version. There was an update to 19.1.3 recently, so it may be worth trying that.
Also try a preference reset after updating, if the update does not resolve it.
thanks, wasn't aware of the new version, now it runs. Not sure what the issue was, maybe stupid user ;-)
