I wanted to install and try Laserweb, but something's obviously wrong,

If this is how I need to install Chromium, I guess I’ll wait till I get home to try LW on some other machine LOL

OK, I’ve managed to install Chromium, but the problem stays the same, even after I’ve enabled two WebGL related options in chrome://flags

@Mishko_Mishko ​ I’m still surprised.

@Mishko_Mishko @Ariel_Yahni_UniKpty As I posted before, I chased this issue for 3 days and finally a new video card fixed the problem. If all the software fixes do not do the trick it is a combination software/hardware with the video card and drivers.

@HalfNormal I also think it’s the card issue. Doesn’t make sense to browse the net for a couple of days looking for the solution, as this is not a machine I will ever use to control the laser. And I don+t even have any card yet, so plenty of time to test the software. Thank you all anyway.
