are you using a dx9texture? or any other texture? select the texturenodes in inspektor and select a specific texture format (there are many to chose from!). if you don’t need the alphachannel use a format like X8r8g8b8 or one with no forth component at all.
today we test the strechtmode (one big desktop on 2 displays)
fullscreen mode works fine with v4 while the resoultion is not higher than 2560x1024.
but if we change the native displayresolution to 3200x1200,start v4 - create a dx render node - we got a grey renderwindow and the errormessage above.
so… we have nothing else in the patch… just the renderer node…
maybe direct x cant handle this display resolution?
