D23105: WIP: [platforms/x11] Cleanup GLX backend

romangg added a comment.


  Some observations:
  
  1. Calling glFinish or not does not seem to influence the repaint rate. I believe instead this is done implicitly by OpenGl if there is no explicit swap event
  2. The delay timer works fine when there are swap events. Without it we are too late for some reason. This must be connected with (1) somehow.
  3. Call to currentRefreshRate does not succeed in retrieving any refresh rate but returns the default rate of 60. This issue should be independent of this work.
