Setting fontGlobalScale in Options causes error

[felixfaire]

Trying to set the font scale in the initialisation options causes an error.

ui::initialize( ui::Options().fontGlobalScale( getWindowContentScale() ) );

results in:

Assertion failed: (GImGui != __null && "No current context. Did you call ImGui::CreateContext() or ImGui::SetCurrentContext()?"), function GetIO, file /Users/felixfaire/Developer/Cinder-0.9/Cinder/blocks/Cinder-ImGui/lib/imgui/imgui.cpp, line 2638.

in GetIO()

Most other options seem to be ok.

Setting this after initialise() works as a workaround:

ImGui::GetIO().FontGlobalScale = getWindowContentScale();

FWIW this is exactly what I'm doing on Windows 10 to use ImGui on a high-dpi aware display. It's working great (as long as I do the setting on GetIO().FontGlobalScale like you did above).
