black map problem

βurak · December 28, 2021

hello, sometimes when I go to another server and then enter my own local server, the map goes black like this and does not fix until I restart the mta.

what could this be due to?

this is how it is normally

client:

fixed the problem is that the map is too high resolution, I reduced the map to 2k

no problem now

Can confirm there may exist some issue in dxCreateTexture. I have also encountered the same situation.
