Need help fixing vsync tearing with dual screen OpenGL (HDMI + DisplayPort)

Hi,

Your issue looks duplicated with one of the old issue

screen tearing when dual monitor

hello, nvidia jetson tx1 connects two screens. #xrandr screen 0： minimum 8x8,current 2000x1024,maximum 16384x16384 DSI-0 connected 720x576+1280+0 (normal left inverted right x axis y axis) 0mm x 0mm 720x576 59.88*+ HDMI-0 connected primary 1280x1024+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x1024. 60.00*+ But, there is a screen tearing with dual monitor. Then I use HDMI-0 only,there is no tearing. How to display the screen correctly? I would appreciate any …

Please try to use EGL+ GL sample to see if you can still see the tearing + frame rate drop issue.

The support for GLUT seems still not good.
