Multipage images are displayed out of sequence and pages are repeated.
This happen when browsing the pages rapidly.

There's a dirty rectangle algorithm in the VNC library code that compares rectangular areas from the current bitmap with the previously transmitted data and only sends the changed pixels. However, reading the whole screen to find those dirty areas is slow on some video boards (it's actually done in smaller segments to improve response time), and even slower with the BScreen copy-the-whole-screen-to-a-bitmap technique. ...

That could be an interesting way of doing it, which would also speed up screen reading since it would reside in main RAM, not the occasionally much slower video memory. On the other hand, it would be simpler for the user to understand a program that merely shows what's on the real screen, remotely. A virtual video card (RemoteHWInterface) already exists for something like this, though I don't know the details. It should be immensely useful for ...

Wasn't something like this needed in the app_server for the VirtualBox video driver? I've been trying to build the VirtualBox additions but the compile fails. Gcc complains about -fpic . My next step is to run though the commands manually. Has anyone gotten the additions to build? On Fri, Mar 27, 2015 at 11:10 AM, looncraz looncraz@xxxxxxxxxxx wrote: ...

Hi all, I have done a bit of requirements elicitation [1] on the trac wiki, namely on ARM microarchitectures. Or in other words, I am trying to gather information such as developer ownership of ARM development hardware, so we can work out which devices we should try to target. It will also be helpful for people who are looking to buy an ARM board, but want to get one that is more common among Haiku developers in the hope that it will be supported sooner. ...

I'm not certain as to how VNC remote viewing is handled, but I imagine it uses the RemoteHWInterface in the app_server, which will not enable the hardware cursor, so will always use a software cursor.
