Lua Widgets make Script Editor Unusable due to Lag

This bug occurs whenever I am in the script editor and have a Lua Widget already open, or open a Lua Widget while in the script editor. An empty script will still lag.

This bug is reproduced by enabling NVIDIA G-SYNC on my 240Hz monitor, although I’ve heard from another that this is also an issue on 144Hz monitors.

The bug happens in every place I open

The bug has been occurring for a few months now so this is not related to any recent updates.

As more and more of the Studio widgets are converted to Lua Widgets I’m scared I’ll soon have no choice but to use an external editor unless this bug is fixed.

System Details:
Razerblade 15
Intel® Core™ i7-8750H CPU @ 2.20GHz
NVIDIA GeForce GTX 1070 with Max-Q Design
Intel® UHD Graphics 630


I understand this isn’t much help, so if anyone has more questions just ask!

Hopefully the edit is an improvement. I found turning of NVIDIA G-SYNC solved the issue.
However none of these mention Lua Widgets which cause the editor lag.
