Display issue of vrep

Some widgets of vrep flicker when simulation is not running. When simulation starts, these widgets become black background. Does anyone know what's going on? My vrep version is pro EDU 3.3.1.

Hello,
what happens if you resize the left elements while simulation is not running? Does it still flicker?
Cheers

Hello,
They are normal when I resize them. When the simulation is running, they also flicker. If I click them, they show the contents. Then they flicker and become black again. The problem mostly happens when the simulation is running.
Cheers.

Hello,
this happens on some machine, but very rarely. You can probably change some settings in your graphic card to avoid this problem. If the problem does not resolve, we will prepare a new version where the problem does not appear (but rendering could be a bit slower).
Can you tell us what OS and what graphic card you have?
Cheers

Can you force using one or the other driver/graphic card? Or maybe selecting a generic driver?

Hello coppelia,
You mean using GTX 960M? It seem the system is using intel graphics card for display.
Cheers

It is difficult to debug without having the exact same set-up here. But we'll try to prepare a special version in a few days.
Cheers
