Offline map flickering

Hi!
So I have downloaded offline maps and when I am using an offline map it flickers everytime I scroll across the map. The map goes blank for 5-10 sometimes 30 seconds then comes back. Does not matter how close or far I am zoomed or if I'm panning 15 ft. Or 15 miles. Goes blank...
Wait..then comes back. Any ideas?

A video would greatly help. This is not normal or reported before.

Does this happen with Google maps? Is the behavior seen with maps of offline lists or just the Live map? If just Live, do you have auto refresh on? If Live, are there lots of caches within the map boundaries? Does this happen when you first open the app or later after using it awhile? What offline map source are you using? Is there a theme on for the map?

The more information I have the better I can help determine what the issue is.

Works fine on c:geo oddly enough if I use the maps downloaded from cgeo the flickering stops not sure what source cgeo uses but I'll just use those maps

Google maps works fine no issues with any other map. I am using the same exact files for geooh that I had previously downloaded for cgeo just changed the alt map directory to the cgeo folder. Unfortunately however I just opened the app again a moment ago and it's back to doing the same flickering again as it showed in the video I sent 🙃

I couldn't replicate the issue.

Try this... point the offline maps directory to another folder (doesn't matter whether there are any maps in it). Restart Geooh and open Live which should be blank maps. Go back into settings and point back to the original maps folder. Restart and try again. This should force the app to clear out the tile cache used by Mapsforge in case somehow bad tiles got in there.

Let me know.

I tried this and didn't work. I did end up fixing it by deleting all the map files off the device. And reinstalling them through cgeo and it appears to be working now. If it starts again I'll let you know. Thanks as always for the quick help!

When the flickering started I had tried using my old original cgeo maps, and the maps downloaded through geooh I had tried using a 2/3 of the different sources listed in geooh. No theme was used in either app. My only guess is maybe the map data was corrupted? I honestly have no idea.
