This partially reverts commit cc0226fad05a6796f50723554c10b1bbd02de7b1. This commit caused high CPU usage in app_server. The double buffering in ActivityMonitor is not to avoid flickering, it allows to draw just a few pixels of the the curves at each update, and reuse most of the bitmap from the previous run. Removing this means all the curves are fully redrawn at each update, resulting in higher CPU usage (one core at 30% on my machine with 5 different graphs). Keep the part of the changes removing code for custom background drawing. B_TRANSPARENT_VIEW flag can be used instead.

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.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
