Is Unreal Engine for game developers or for engine troubleshoothers?

4.10 New Bug: Enabling World Composition breaks Playback of Startup movies
4.11 Fixed
4.12 Broken again

4.10 New Bug: Interacting with 3D Widgets broken (no mouse click received)
4.11 Fixed
4.12 Broken again

4.11 SteamVoice works perfectly.
4.12 SteamVoice broken (sound cuts out).
4.13 Fixed as UE-34081 but still broken.

I’m getting so tired of this i even stopped reporting the bugs on the answerhub already since staff fails on replicating issues when you even provide 2 sample projects, one working, one broken. https://answers.unrealengine.com/questions/446592/steam-voice-chat-cutting-out.html

It get’s worse with every new engine version coming out. In 4.12 you cannot even keep the preview enabled of the content browser, it will allocate memory constantly and ruin your framerate.
