Confirm that happening on both 4101 and 4104 with OpenGL enabled.
Custom titlebar (Adaptive or Daneo) flickers quite frequently, while making sidebar flicker requires the window to be resized slowly and in small steps.
Are you still seeing this in build 4169? There have been various OpenGL related fixes since 4101.
Not experiencing issues on my Dell XPS laptop when using the Integrated GPU, but only on the dedicated GPU. The title bar is the only part flashing now. Compared to the OP, I'm not getting the same flashes with the sidebar / views which is great, thanks.

Adaptive Theme, Breakers Color Scheme, Build 4170
iirc my original issue was on a desktop system with a NVIDIA GeForce GTX 1650 Super which I don't have access too atm so my results may differ. I've selected the dedicated GPU for Sublime Text from NVIDIA's control panel to try an mimic a similar environment.

Also see titlebar flickering with Adaptive or Theme - DAneo, which both use themed titlebars.
