Hi everyone, I noticed that my development builds with enabled script debugging are getting an extensive performance hit. A lot more then I'm used to. The Profiler tells me it's primarily bc of OnGUI related unity code (BeginGUI() EndGUI()) I build with .Net 4.x, IL2CPP, C++ Release I use OnGUI a lot for my debug GUI. An older build I did with 2018.2.6f1 does not show this behavior. My release builds (stripping out all OnGUI methods) are running at about 60fps , my debug builds formerly did run at about 30fps but now around 3fps. I didn't change anything related to the GUI nor does anything else show a significant performance drop in the Profiler. Is this known / does a work around exist? ps. currently I'm building with 2018.2.15 with the same result. Edit: to make it clear: as soon as I disable script debugging in the build settings the speeds are up again.
