[fixed] 1.0.9.5.1 beta] Initial black rectangle

[Dreamy]

Hello,


please, why UltraVNC, unlike other VNC servers, sends initial black full screen size rectangle? For example I would like to get only 100x100 pixels from [0,0], in raw encoding. I send regular FramebufferUpdateRequest for 0 0 100 100, and what I get? Black fullscreen rectangle.

And it's the same thing when I try serverside scale.

Example for 800x600 screen:
-> 0F040000 (scale 1/4)
-> 03000000000000C80096 (get whole new screen)
<- 0F000320025800C80096D201 (reply about successfull scale change)
<- 00FD0001 (yeah, got one new rect)
<- 000000000320025800000000 (why? why 800x600??? i never even asked for 800x600!)

if i'm not wrong and if related...

i remember is a flash screen for alert remote user there is someone connected to his computer.

advantig has made a patch to vncviewer but never been include in the public code
vncviewer /noflash

otherwise maybe priority and missing file like schook.dll and/or vnchooks.dll
look at ultravnc.ini aka GUI winvnc properties (not admin properties)

Thanks much for reply.

b) didn't help at all, still sends fullscreen, raw, black, rect.

Code: Select all

-> Scale 1/8: 0F080000
-> FramebufferUpdateRequest: 03000000000000C80096
<- Scale reply: 0F00032002580064004BC101
<- FramebufferUpdate: 00FD0001
<- Head: 000000000320025800000000 <----- 800x600 black raw

a) can you give me some more info? what patch? viewer? not server?

It's working perfectly, thanks!

winvnc.exe sends black rectangle:
When I don't send SetScale before FramebufferUpdateRequest, initial black rectangle is not sent.
When I do (and I need to), it is sent

definitively fixed, confirmed by antilopa
