- Fix a bug that glx_bind_pixmap() doesn't work with mesa drivers.
Thanks to Janhouse and mkraemer for reporting. (#7)
- Use stencil buffer to attempt to eliminate potential double-paint
issue in glx_render(). X Fixes doesn't guarantee the rectangles in a
region do not overlap, and this may cause some regions to be painted
twice, which would be a problem if we are painting transparent things.
Now the target window must have a stencil buffer. Compiz uses its own
region implementation to deal with this, but as a lightweight
compositor we can't really do the same. It may have a positive or
negative effort over performance. Callgrind result indicates basically
no change in performance, but this may or may not be true.
- Correctly distinguish GL extensions and GLX extensions. Sorry. :-D
- Handle screen size. Thanks to tsmithe for reporting. (#7)
- Rename OpenGL backend to GLX backend, because, we might have a EGL
backend someday.
- Add configuration file option `backend` to specify backend. Add
`backend` to D-Bus `opts_get`.
- Add OpenGL shader compilation code, but currently unused.
- Minor adjustments.
- Known issue: Window content doesn't get updated in VirtualBox,
probably because its OpenGL implementation requires constant rebinding
of texture. But that's really slow...
- Known issue: Blur feature is still unimplemented in GLX backend.
- Add experimental OpenGL backend (--opengl). --blur-background is
currently not possible with this backend, because I'm still trying to
find a proper way to do blur with OpenGL. Flipping backend on-the-fly
is really hard, so it isn't supported right now. No configuration file
option exists to enable this, because it isn't stable enough.
- Add `opengl-swc` VSync method that uses SGI_swap_control to control
buffer swap, with OpenGL backend. (#7)
- Fix a potential read-from-freed-memory issue in paint_all().
- Correctly reattach GLX context after fork.
- Dump error text in error(). Add GLX error code handling.
- Code clean-up.
- Known issues: Region operations take a lot of time in glx_render().
I'm hesitating about what to do.
- Create OpenGL context only after initializing overlay, which fixes a
bug that --paint-on-overlay does not work with OpenGL VSync. Thanks to
tsmithe for reporting. (#7)
- Fix an assertion failure that occurs when a window is reparented to
the root window then immediately to another window. Thanks to smlx for
reporting.
- Add extra debugging info for ReparentNotify.
Work is needed to disable the respective Move Tab Left/Right menu options
when the tab is already the left-most/right-most tab.
This partially resolves bug report 1067.
- #91: Use pkg-config to find drm.h to avoid issues on FreeBSD. Thanks
to hun7err for pointing out and providing patch.
- #89: Add default shadow exclusion rule for notify-osd. Thanks to
DanielRS.
- Check for abundant positional arguments.
- Use paint target window (root window / overlay window) instead of
ps->reg_win to create GLXContext. (May have negative effects on OpenGL
VSync.) Add new OpenGL helpers functions, to prepare for the new
OpenGL backend.
- Dump more info of a PropertyNotify with DEBUG_EVENTS.
