So, recently I've been playing Super Mario Galaxy on my device and, while playing using Vulkan, everything worked just fine, but then I decided to test OpenGL to evaluate performance, and while it ran much faster than Vulkan, the EFB access to CPU isn't working properly... The stars aren't shooting properly and it's really hard to enter the galaxy choosing screen as the cursor seems to change randomly into a hand so I can grab the star in the domes...

But the access is actually working, as the Gods Rays from the sun are properly emulated when EFB access to CPU is on even on OpenGL... so the issue is only with the cursor...

Am using PAL version of Super Mario Galaxy, if that helps...

Can anyone try to replicate this issue? Am using the latest build as of today...

Yeah, the game can't tell what's on the screen unfortunately. It could be an issue with the graphics drivers (it works on Vulkan) or we could be using a feature that doesn't work in OpenGLES. I don't know.

I see... it's funny because graphics effects that depend on the feature work just fine, like the gods rays (that tanks performance heavily, btw), and even the cursor seems to work intermitently... I even managed to enter a level once and it ran much faster than Vulkan....

I have the same problem too. But... This issue doesn't exist on the custom build of dolphin so try using that for now.

I'd rather use the latest build with Zackhow's Touch Screen IR Sensor for now, as everything works perfectly on Vulkan on my end and it's perfect to play SMG...
