relation list not updated #271

Open fkv1 opened 2 years ago

fkv1 commented 2 years ago

When I click the "Download more" button and a member of a previously not loaded relation is loaded, the relation list sometimes does not get updated. The update happens later at apparently random times, like when I move and edit around, or when I switch to another application and back to Merkaartor.

This is most obvious for multipolygon relations, when a member (border) is loaded but the relation is not; but I believe it happens with other relation types too.

I've experienced this problem since I updated from 0.18.2 to 0.19.

PS: Switching to another application does not work, but switching to another virtual desktop and back does, and minimizing+maximizing Merkaartor works as well. Seems like some refresh is missing on "Download more" but happening when the whole Merkaartor window is redrawn.

Thanks for reporting. Could you provide additional info to help me reproduce the problem?

  1. What platform/build do you use (package? from source?)
  2. Example coordinates where it can be seen.
  3. Screenshots/short video of the bug happening.

Definitely sounds like a missing event somewhere, though I don't seem to catch it, maybe I'm looking for the wrong things.

1) FreeBSD ports system (compiled trough a framework) 2) Move viewport to way 1004384905 and click "download more". It's a member of a multipolygon relation, but the relation list remains empty. 3) merkaartor_emptyrelationlist

Trying to create the screenshot, I found out an even stranger aspect: If I start Merkaartor, then switch to Gimp on another virtual desktop, fire a screenshot with 10 s delay, then switch back to Merkaartor, then "load more", the relation list does load. I had to have Gimp on the same virtual desktop to create the screenshot with loaded map data and empty relation list.

Same if I open Merkaartor, minimize+unminimize the window, then "load more" -> relation list complete.

All I said about the relation list also applies to the "Ways" and "Nodes" tabs. Whenever the relation list is mistakenly empty, the Ways and Nodes lists are also empty.
