When source code has errors: The Manifold plugins makes IntelliJ very slow (delay of 7 to 13s!)

I’m very sorry, keep writing about issues, I find manifold actually brilliant.

Describe the bug

For some days, I noticed that IntelliJ becomes very slow as soon as the code has errors.

Now, unfortunately, I was able to trace the problem back to the manifold plugin:

Ex. 1: No optional IJ Plugins are enabled: IJ is fast

I finally had time to disable all plugins - and then IJ is fast, see this example: I fix a bug in my code and return a string in the Code. You can see the characters while typing the returned string content:

Ex. 2: Just the Manifold Plugin 2021.2.17 is enabled: IJ gets lags

Now, I just enable the Manifold Plugin, 2021.2.17 (I’m pretty sure this bug crept in before version 2021.2.16). I fix the same bug in my code as above and return a string. Maybe important: As soon as I start modifying null in "null", then IJ is blocked. Now, you can not see typing the characters in the returned string. After a delay of about 11s the complete return statement is displayed:

To Reproduce Steps to reproduce the behavior:

I think it is fixed!, thank you very much! 😄

Good evenin @rsmckinney

after many months I finally get back to developing SW with java and after two weeks of working, I didn’t have this tedious error anymore 😃. I am very happy you were able to fix it, thank you very much!

I also saw that Manifold is now free and so I hope that this licensing is also fair for you. I wanted to recommend Manifold in two commercial projects so that they then buy licenses 😃, but because of this issue here I had to wait and I was also not sure if / which Manifold components you rate as mature.

Thanks a lot for all your work, kind regards, Thomas
