doing some online tutorials on Image detection models and encountering a libGL error preventing displaying the result. .
(works ok for the CSI cameras however). See below

The error seems to be generated by the jetson_utils.glDisplay() function…
The puzzling thing is that the error is random, at the moment occurs only when attempting to use a DetectNet model and display from web cam the result but not when using ImageNet models (and other openCV application) but again the beaviour seems not to be predictable I saw that this has been reported in many Unix forum and briefly also here but I could not find any satisfactory solution. Using Jetson Nano 4 Gb with JetPack 4.6 and would like not to reflash the ssd card as it has been a painfull experience to rebuild a working the system after upgrading to this version recently.
