ArmorPaint 1.0 alpha-6246a99, Windows

Issue description: Been having bugs that make the camera act odd and some tools not work properly. Using ArmorPaint for producing liveries for Assetto Corsa Competizione, unsure if it works with other models or if it's just with ACC models. The camera controls will start "flying" the camera instead of rotating the camera when doing the input to rotate. Some tools (like eraser) sometimes stop working properly when the bug occurs. Unsure of what can be done and unsure I can reproduce it to a T. (happens some times and not other times)

Steps to reproduce:
Unknown how to reproduce. I was working and I mirror placed a decal, and now when I try to rotate the camera, the camera flies where I'm pointing and the eraser tool wouldn't erase the mirrored decal on the layer. Exiting and reentering software does NOT fix the issue. It almost becomes embedded in the file itself.
