So recently I have been having an issue where anything that requires WebGL just doesn't wanna work on Opera, be it SculptGL, PaintBerri or anything else. I can't seem to figure out why; everything I could find that addresses this issue is from 2011 or some other year with probably-super-outdated info (mostly 2011). This stuff works on my backup browser (Firefox), so it's definitely not an issue with my computer- it's something in Opera itself. This also only recently started happening, with no settings changes that I can remember in between when it was working and when it wasn't.
For the record, I'm using Opera version 36.0.2130.65, and I have hardware acceleration off because I've found it breaks more things than it helps.
What's going on?
EDIT: Ah, I suppose I should be more clear with what I mean by WebGL "not working". It's acting as though WebGL isn't supported by my browser, even though I KNOW it is.
