Hello forum,
when my Edit page has a timeline over 2 hours long, the vertical clip edges become unsharp. It gets worse towards the end of the timeline, and it depends on the timeline zoom. This just affects the clip rectangles; the red selection rectangle remains normal at any timeline position.
It seems to be a rounding error that varies with timeline position and zoom factor. Maybe the clip rectangles use a 32 bit floating point, while the selection rectangle uses a 64 bit -- or something like that.
Here are some screenshots. Timeline zoom was always at maximum.
At 1 hour, the clip edge is sharp:
At 2 hours, the clip edge is blurred:
At 7 hours, the clip edge disappears. The colored filling still has an edge, but the edge is at the wrong position (it should be at the red selection rectangle). I used 7 hours here as it shows the effect better. The effect already occurs at 3 hours, depending on the zoom factor:
It makes the visual tools unreliable. Also, when clips have the same color, the cut cannot be seen at all.
This is on an iMac with Resolve 18. I think it occured in version 17 too.
Frame rate is 50 in all clips and in the timeline.
