Can confirm that the Grayflag Syria mission is where I run into it most commonly - not just with scroll zoom but also using the Zoom In / Zoom Out tools from the top bar. The theory on their Discord (apologies if this has been brought up elsewhere) is it occurs for AMD GPUs on maps with lots of "drawn" elements, in Grayflag's case zone boundaries, frontlines etc.
Interestingly, I don't seem to get it on Lima Kilo's Flashpoint Levant map, which also has regional borders and suchlike drawn on it. Guess there's a critical value somewhere between the two. Other difference would be that Grayflag has the UH-60L mod enabled, don't know if that could affect it.
Once encountered, the issue persists even after leaving the server (see second video).

Edit: Saw the requested details in the other thread, that server was:
DFA Grayflag Syria, server1.dfa.wtf:10308, run by Graywo1f and Grimes, recorded this morning on an AMD RX 480 8GB.
