I've been pester by a weird symptom of U3D 2020 editor. Issue is that, the Editor would randomly itself to Professional Editor Theme(Dark mode). I could switch back to Light mode from Preference easily. However, it still switch to Dark mode just randomly, and some time it became a weird combo-mode, that the framework of Editor is Dark mode, but the Icon is in Light mode, or vice versa. So....not a really big deal, but really annoying. Finally, I'm using 2020 1.0f1c1 personal ver On Win10.
