Hi, I'm also having this issue.

Describe the bug I was only looking at my screen when it happend. I was not clicking at the time. I actually recorded this, as I was making a tutorial at the time, so can send this over as well.

To Reproduce 1.) Choose a project on MS4Web. In my case, I chose this one: https://web.mapswipe.org/#/en/projects/-NwG8EbUqZW7t0R8TxKq 2.) Click the > to advance to further columns 3.) Look at the screen to swipe. 4.) Suddenly the screen goes white. 5.) Refreshing does seem to bring the screen back, but it sometimes takes some time.

Expected behavior I would expect that I can continuing clicking through without the webapp crashing.

Screenshots Ack, I forgot to grab it before I refreshed, but it looks exactly as above. Let's see if this video link works here: https://github.com/mapswipe/mapswipe-web/assets/15011784/4e0467d9-5460-4321-93d6-73b390785997

Desktop (please complete the following information) M1 mac Ventura 13.2.1 Chrome 124.0.6367.158 (Official Build) (arm64)

Here are some points that may help identify and address this malfunction;

• The only action necessary to trigger the white screen is clicking "select" on a project. The white screen error can occur while still looking at the "How to Contribute?" pop-up i.e. having not interacted with the task in any way, no other input what so ever.
• There is certainly variance in the time period after a task is selected untill a white screen error occurs. I have not measured this, but I think that this time period has a negative correlation with the amount of interaction a user has with a task, and a positive correlation with the amount of time a user waits before refreshing the page.
• I have only encountered this malfunction when working a task in a "find" type project. I have never encountered it while working on a task within a "validate" type project.

I will also make an ammendment to the previous comments in this thread. Reloading puts you into a different task than the one you were just working on. Work on a task appears to be lost given the lack of saving; I was served a task I previously worked on (and marked) with no marked squares.

I would add that this only seems to happen on the Identify Buildings tasks
