Povray terminates due to uncaught exception: 'NSWindow drag regions should only be invalidated on the Main Thread!'

[myan18]

Hi,

I installed Povray 3.7 last December on back then new MacBook Pro (Mojave). Povray ran fine for a couple of months. Last week when I tried, Povray failed to run. I just upgraded the whole MacPorts including Povray. However the problem persists. The complete output is attached below.

Any hints? Best, Max

[jmroot (Joshua Root)]

Error messages seem fairly self-explanatory; the OS wants some operations to only be done by the main thread, and the app is doing them on other threads. I guess this is a new constraint added in more recent OS versions. Probably something that upstream needs to fix.

[myan18]

Replying to mf2k: However I did not get the answer. What or who is "upstream"? Will it be fixed within a certain time frame or the problem will be hanging indefinitely? I am seriously considering to get a backup Windows machine just for being able to use Povray...

[kencu (Ken)]

upstream refers to the people who wrote the software.

Macports is a build infrastrucure, and controls how software is built, which compilers are used, what supporting software is used, etc.

But if the actual software has a bug in it, that's a problem for "upstream".

port gohome XYZ

will take you upstream, where there is usually a way to submit a bug report like this.

[fstonedahl (Forrest Stonedahl)]

Until this gets fixed upstream, here's a work-around: I found that you can pass the -D command-line option to povray, to get it to render in the background (i.e., without displaying the image as it progresses), and it should still generate the PNG file output just fine.
