Summary | 0009365: Unnecessary glFlush() call in vtkOpenGLFreeTypeTextMapper::RenderOverlay() | ||||||||
Description | In VTK 5.4.2 and older versions there is a strange glFlush() call in vtkOpenGLFreeTypeTextMapper::RenderOverlay(). Even if it leads to no visible consequences on most "native" Linux X servers (neither locally nor through a remote connection), on some Win32 X servers like X-Win32 or Exceed it results in frame buffer swapping, and everything drawn after the first text label goes immediately to the active frame buffer and appears on the screen. I have tried to comment glFlush() call (most likely, it remains there since some debugging). This resolves my problem, thus I attach the corrected source file for validation and testing. | ||||||||

I tried this change on my working copy and 1) no new test failures were introduced 2) it does not cause any problems in my app, including where I use vtk to draw text. flushes are expensive, so if this really isn't needed, that'd be nice. Assigning to François because I know he knows about ogl&vtk. :) |
