When switching back to a kmscon console, the screen is black until an input event occurs (keyboard or mouse). This is particularly visible with drm3d (hwaccel), even if the fix applies also to drm2d. Signed-off-by: Jocelyn Falempe <[email protected]>

Have you turned dpms-timeout on or off ? |

In my testing I didn't enable DPMS timeout. The bug is that when you switch VT, the first frame is black, and kmscon will redraw only if something changes (so either mouse or keyboard event). |
