Map stuck for many seconds while driving

While I was driving in Taichung (Taiwan), the map was continuously getting stuck for many seconds. It seemed like an app has very heavy load (a lot of rendering taking place?), e.g. sometimes after few seconds new label popped up on the screen or it took time to zoom out.

The GNSS location update from the phone was fine as guidance panel with next instruction was updated smoothly (see mismatch on screenshot).

When I drove out of the city, the problem was not visible. I have used the app in few other cities in Taiwan (e.g. Kaohsiung, Tainan, Chiayi) and it is the first time I have experienced this issue. I have updated the app and the map to the latest but the problem was still there.

As you can see in the screenshot, there is a lot of house numbers. Could the app stop showing house numbers in driving mode? Maybe that would help.

House numbers could be unrelated, but we already discussed that they pollute the screen too much. @pastk @vng let's try to remove them for vehicle (navigation) style for all zooms except the last one? I'll test it on a branch.

IMHO, house numbers is the key information in city navigation mode. Is there a discussion about them?

There was a discussion here #1935 recently

ATM house numbers are displayed starting at z16.
Do we know to which vehicle speed this zoom level corresponds? (when auto-zoom is on)
When navigating house numbers are usually needed when very close to destination and slowing down to e.g. stop by a particular building number.
So maybe makes sense to display them starting at ~20-30kph speed. What zoom level this will be?

Discussion makes sense in general map view. But my point is about Navigation mode. Now they draw in 17-19 and I think its good.

Navigation mode uses z16- also. There are two sets of rules:

area|z16-[addr:housenumber][addr:street],
node|z16-[addr:housenumber][addr:street]
{text: name;text-color: @building_label;text-position: center;}

I guess above is for standalone address tags not attached to buildings.

area|z17-[building],
node|z17-[building],
{text: addr:housenumber;text-color: @building_label;text-position: center;}

And this is the case for buildings with addresses attached.

Ah, yes. So they definitely should be equal. I propose to make [addr:housenumber][addr:street] starting from z17 like buildings in Navigation Mode.

My proposal is to draw building addresses from z18 in navigation mode and see how it helps to clear the map and see more important names. I'm ready to test it.

As I showed in organicmaps/organicmaps#1656, house numbers are only part of the issue. If you are using bike or foot navigation in a city, all the POIs shown destroy the performance especially when using perspective view. Ideally the map engine should take into account the perspective and the zoom level to decide when to show POIs or house numbers.

Can you tell at which speed roughly house numbers appear on the map ATM?

BTW atm on the "regular" map we prefer to display building names if they exist, however in navigation mode house numbers are preferred.
For me a building name is a better navigation landmark than its house number, however a building name will take much more screen space...

@tomekem-gh do you store maps on SD card? If yes, can you please try to move the downloaded map(s) to the internal memory (or better to delete them, set storage to internal device location, and redownload again), and try to reproduce the bug?

[Slow/counterfeit/fake/wore off] SD cards very often cause lags according to our user reports.

No, it's on internal memory, I don't have SD card.

I cannot reproduce the problem right now as I don't live in the city in question (and I might not be there any time soon).

What are my options? Would reproducing it with fake GPS provider do? Would logs help you?
