Problem:
DaVinciResolve crashed, when I quickly zoomed in-and-out on the timeline (hitting alt-key and quickly turning the mouse wheel up (until maximum zoom is reached) and down, as well as dragging the (-)(+) slider above the timeline to the left and right).

The whole story:
I installed 14.0.0.078 today (previously 14.0.0.05x something was installed), imported dozens of clips and everything works. After about 30 minutes i quickly zoomed in and Resolve Crashed.
Going back into the project and zooming in, it instantly crashed again.
So I restarted Resolve, started a new Project, imported a completely different (other codec, other resolution, ...) footage file and zoomed in and it crashed.
I could do this with all my projects and all sorts of new projects (with all sorts of footage).
Then I wanted to narrow down the reason and switched the timeline-view-options from "show as much frames as possible in the timeline" (the first option) to "show no frames" (the last one).
Since then I cannot reproduce the issue, even when I switch back to the timeline-view-option i previously had.

Edit:
After a Computer reboot, the crash happens with 100% reproduction rate (if the show-multiple-images-on-each-track-in-timeline-option is set).
Sometimes after a crash, every consecutive restart of Resolve turns the Resolve-App in a really slow-mode (single threaded?) where playback is laggy as hell. As long as Resolve is in this "slow-mode", the reproduction rate for the crash is 0%. Until i Reboot my Computer, and I have 100% reproduction and "fast-mode" again.

Here is the Crash Log:

My System:
14.0.0.078
Windows7 Professional SP1
i7-2600 @3.4 GHz
18 GB Ram
Radeon HD 6900

Additional Infos:
The issue seems to be connected to Multithreading:

If I tell Resolve (via TaskManager) to only use one logical core, all my crashes (including the above mentioned Timeline-zooming) disappear (though the program is to slow to be usable when used single-threaded).

Same here on latest version 16.1... on win 10.

Same here with 16.1.2 on 2017 iMac 5k 27” with i7, 40g ram and 1tb SSD / 3tb SATA (fusion).

Interesting this is happening on both Mac and PC. But also interesting it doesn’t seem very wide spread. I imagine most users are constantly zoom scrolling in and out timeline.

I just posted this issue today, and somehow missed this post when searching for the issue.
I found it does not behave like this with my trackpad as the scroll device.

Hello All,

I am having the same problem! I have changed nothing except update my drivers and now everytime I launch DaVinci, it works as normal but as soon as I use zoom on a clip it crashes, sometimes my whole computer.

I have restarted my computer, ran as administrator, completely uninstalled, and even tried DaVinci Resolve 17 - my issue is still there.

Did you guys find a fix?

I also have this problem every time i open Davinci Resolve 16 and it keeps crashing whenever i try to zoom in
