Description

When I put my PC into suspend-to-RAM and wakeup it again not all parts of the editor is rendered correctly: 2018-01-07-104732_2058x1409_scrot

When I move the cursor some lines down it looks like this: 2018-01-07-104258_2058x1409_scrot

In some older versions :redraw! helped, but this not the case anymore. The only way to fix it is to resize the window. I'm running Linux.

Research direction
Investigate the rendering pipeline in Oni, particularly around suspend/resume events. Look at the use of requestAnimationFrame or canvas context handling. Check if there is a missing redraw trigger after system resume. The issue mentions that resizing the window fixes it, suggesting a layout or repaint problem. Consider examining src/Editor/NeovimEditor.tsx or related render files for how the editor canvas is managed.
