Current limitations of the Evas GL renderer

[swift-kim]

The Evas GL renderer (#67) currently has the following limitations.

Known issues:

• Not works with the webview_flutter plugin.

Things that might be improved later (non-critical issues):

• Support hardware keyboards (currently is_ime is always true).
• Fully implement screen rotation. → Implement rotation on TizenRendererEvasGL engine#277
• Support screen resizing (currently disabled because elm_win_aux_hint_add is available since Tizen 5.5). → Implement TizenRendererEvasGL::SetGeometry engine#214
• Reduce memory consumption on TV devices (+28 MB when compared to the Ecore Wl2 renderer).
• Non-fatal warning message when running on TM1 (Tizen 6.0).

  tizen_renderer_evas_gl.cc: SetupEvasGL(608) > Failed to create evas gl context with EVAS_GL_GLES_3_X, try to use EVAS_GL_GLES_2_X,
  

• A black screen is displayed until the first frame is drawn. → Blank screen is displayed when launching app on Evas GL engine#222

Let's suppose the window is initialized as follows { width: 720, height: 1280 }, In this situation, depending on the rotation, these >show the following results:

When the window rotation is 90 or 270 degree
evas_object_geometry_get returns: { width: 1280, height: 720 }
but
ecore_wl2_window_geometry_get returns: { width: 720, height: 1280 }

The above facts have recently been revealed.
GetWindowGeometry is used the following and related problems occur in all of the following:

1. Create rendering surface.
2. Handle rotation event.
3. Send flutter point event.

• Non-fatal warning message when running on TM1 (Tizen 6.0).

After flutter-tizen/engine#288, it doesn't appear on logs

It works fine.

[swift-kim]

It works fine.

@bbrto21 Did you test on a real device (TW3 or Active)? I can't test because my watch doesn't have an Internet connection.

[bbrto21]

I tested on TM1. I think I can help you setting up to connect internet in office please contact me.

The Flutter website (flutter.dev) is properly rendered on my GWA1 although it's extremely slow and unresponsive.
