Run render loop regardless of canvas visibility#30
Merged
Conversation
Emit the frame notification each frame in the visualizer render handler, regardless of whether the canvas window is the active tab. The previous approach of conditioning emission on Begin caused tab focus to flicker when operators maintained their own dockable windows. In case both windows were docked and the main window lost tab selection, the other window Begin/End pair was never called and so ImGui reselected the main window tab, which again redrew and selected the other window, causing a loop.
