Bug report: Resolve viewer caches old version of image
Resolve 17b8 running on Windows 10.
Here's a video showing the problem:
Steps to reproduce:
1. Open Resolve and import a PNG or other image.
2. Drop image into timeline.
3. Edit image externally in Photoshop or similar, save, overwriting the previous file.
4. The still frame in Resolve's viewer still shows the old version of the image.
5. Click play and it's still on the old version.
6. Relink the clip and click play. Now the updated image displays.
7. Click stop. The old version now comes back for the still frame.
Preferred behavior: Resolve picks up any image changes without relinking. Resolve shows the correct still frame in the viewer.
