[virglrenderer-devel] WebGL app flickers with virglrenderer

[Ashisha Sutradhar]

Hi All,
We have been using virgil renderer for our internal development with QEMU.
It has made a huge difference and added a massive advantage in our solution so far.

Recently we have encountered an behavior which is as follows:
1.      Invoke Web browser App
2.      Navigate to "_http://www.kevs3d.co.uk/dev/canvasmark/_"
3.      Press "Space bar" to Initiate the test
4.      Observe the screen

Expected Result: The webGL video plays successfully without flickers or crashes

Actual Result: Screen display starts flickering and eventually browser crashes after indefinite duration.

Note: Logs "webgl_log.tar.gz" attached for reference

The logs shows the below error:
vrend_report_buffer_error: context error reported 6 "Chrome_InProcGp" Illegal command buffer 720905

Requesting you help us in resolving this.

Warm Regards
Ashisha
