Missing entries on moderate traffic

[roman-orekhov]

I noticed DebugView++ 1.9.0.28 may miss some OutputDebugString calls. I generate just 15200 calls per 250ms and miss 0 or 1 or 2 strings (seemingly random). I have 10 views opened and they have like 15-ish color rules each. Other capturers like DebugView or WpfTraceSpy capture all the output but I don't have any color rules there.

Have I reached the limit of DebugView++ capabilities?

Is there a hidden setting somewhere to increase some internal buffers?

Can this be related to amount of views/color rules?

Debugview++ was thoroughly stress tested with 100k+ of lines per second, so I think it might be something in the filtering? Can you try opening a new tab without filters too see if the line also not there?

Just checked - not there. My traffic contains almost the same strings during a session, and every run the missing strings are different. That is on the other run they somehow pass the filters

I created a test app and some data here
I open DebugView++ with an unfiltered tab (as well as my other tabs!), run the app with parameter "input.cutdblog", then copy and paste from DebugView++ to text file, remove the columns so that the results are comparable, and saved to "output.cutdblog". My full configuration is also in the shared folder.

hm, very helpful, I will see if I can understand why this happens
