I fired up a virtual machine with Kubuntu, and was unable to reproduce your results.

I did have some issues with the mouse

It's possible some or all of this could be attributed to the virtualization layer though. Could you tell me more about your setup? Are you on i386, amd64, or perhaps arm or something?

Also, are you using a proprietary graphics driver? You can use glxinfo to get more information about which graphics driver is in use.

Hmm, judging by this 4.6.0 NVIDIA 525.125.06, I'd say it's the proprietary driver.

I don't have any Nvidia hardware to test against. I wonder if you'd be willing to try the nouveau driver, or perhaps live-boot a distro which does not include the proprietary driver, and test again.

Let's see if I have time for that. Afaik, libgles2 should work with proprietary drivers as well.

computermouth commented 1 year ago

Agreed that it should. You could also try something like es2gears or $ gcc experiments/sdl2gles2tri.c -lSDL2 -lGLESv2 && ./experiments/a.out to test other programs which utilize gles2
