I just updated to the latest stable version 12.4.1, but all my WMS maps are corrupt now (see attached image). Only a small portion of the WMS map is shown.
The created cached tiles are empty files.
In cannot go back to the previous version (beta 13.0.0-beta426, because it’s not available anymore 
Hey @G_Vandenboom,
From your image, it looks like it might be an issue we reported with SkiaSharp awhile ago, but I can’t really be certain. Can you give us some specifics/configuration about your WMS so that we can identify the issue further?
For now, you should be able to get 13.0.0-beta426 again to resolve the issue on your end for the time being while we work to resolve the issue in a future update.
Thanks,
Kyle
This is the function I use on my mapView which works perfect in beta 426.
mapView.MapUnit = GeographyUnit.Meter
wmsOverlay.Name = "Natura2000"
wmsOverlay.ServerUri = New Uri("https://geodata.nationaalgeoregister.nl/natura2000/wms")
wmsOverlay.Parameters.Add("EXCEPTIONS", "INIMAGE")
wmsOverlay.Parameters.Add("layers", "Natura2000")
wmsOverlay.Parameters.Add("styles", "natura2000:lnv_natura2000")
wmsOverlay.Parameters.Add("transparent", "true")
wmsOverlay.Projection = "EPSG:3857"
wmsOverlay.TileCache = New FileRasterTileCache("C:\ProgramData\GPIcache", "Natura2000", RasterTileFormat.Png)
mapView.Overlays.Add(wmsOverlay)
Kind regards,
Guido
Hey @G_Vandenboom,
I’ve confirmed the issue on my side with the latest code. We are still waiting on a response from SkiaSharp’s developers, but they have not gotten back to us yet.
You can see that issue here: https://github.com/mono/SkiaSharp/issues/2249
Once it gets resolved, we will have a new release build. Until then, just continue using beta 426 or 12.3.21 (which is slightly newer than beta 426).
Thanks,
Kyle
