No, thumbnails have all been generated.
I mean the size of the thumbnails. When I have plenty of small thumbnails on screen, and hover the mouse over the thumbnails, the one under the cursor takes a lot more time to get highlighted (I'd say around one second). > > what's your cpu, your screen resolution, and the size of the thumbnails > where exposure times seem to be the worst? CPU: i7-4790K. OpenCL deactivated (the GPU isn't faster than the CPU on this machine) screen resolution: 2560 x 1440 the size when it's worse is when the zoom level slider is at 21. Best at 1 obviously. By the way I usually use the "file manager" display and not the "zoomable light table". The effect is worse with the zoomable light table, as dragging the light table has a slow refresh rate (when the thumbnails are small). > > we can save some cycles by introducing one more even smaller level of > thumbnails, for very small images on screen.. if that is at all the case > you're talking about?
