Fixes #15548. This change disables immediate drawing of background on expose and makes drawing background a part of the update session. In previous version expose/update separation is incorrect in some cases. For example when view with B_FULL_UPDATE_ON_RESIZE is resized, it will be updated with expose cause, that will trigger flickering. Correct handling should be update on old visible area and expose on area that became visible. If immidiate exposed area erasing is preferred, it need more work to fix. Anyway delayed redrawing cause problems only on slow machine or on slow responding applications, but current master approach cause flickering even on fast machines and on any application that use non-transparent view color. Multiple expose/update requests also seems not work properly.

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
