I was a bit worried at first as I thought a random was trying to initiate a remote connection, but i eventually worked out how to replicate it, and what to google, when i found this post, which is exactly the same thing that’s happening to me. The OP there closed the thread after uninstalling Chrome. Not really a solution that works for me though.
Now that I know that I always get the popup when pinching or zooming on the touchpad when using Google Chrome, I’ve done a bit more Googling and testing, and, weirdly, I don’t even have Googles remote desktop extension added to Chrome. I removed all extensions (mostly about viewing Word or PDF docs) leaving only the GNOME Shell integration extension added.
If I move the slider to “Allow Remote Interaction” and press “Share”, i get the red icon showing in the taskbar and pinch/zoom reverts back to it’s correct behaviour of zoom out/zoom in
I can then zoom in and out with the touchpad as long as that icon is in the taskbar. as soon as I either left or right click on the red icon, it disappears and we’re back to the start where pinch/zoom brings up the popup again.
I had this issue too, fixed itself after adding these flags to the ~/.config/chrome-flags.conf: --ozone-platform-hint=auto --use-zero-copy --enable-features=VaapiVideoDecoder,VaapiIgnoreDriverChecks,Vulkan,DefaultANGLEVulkan,VulkanFromANGLE,TouchpadOverscrollHistoryNavigation%
Most likely you only need the first one so Chrome runs in wayland mode but I’m dumping all just in case.
