OK, after quite a bit of research the bottom line is that this is a mali quirk. There are 2 potential ways both are by specification allowed to sync with the driver - which resulted in a performance issue (covered by this bug) and a "correctness issue" covered by bug 1573014 The performance

Freiza has been slow since the day I received my device, although I don't recall what image I first used on it. It's interesting that there are issues with EGL sync fences - I'm pretty sure we're using these in Oxide on this device. They're blacklisted on krillin with the comment "Testing fences

I'm not familiar with Frieza so can't test any of this myself... If the problem is eglSwapBuffers taking two frames, then that's the same kind of thing we saw in bug 1563287. Even though we measured the client (Unity8 itself) was taking two frames, the problem was actually the server (USC) being

[Touch-packages] [Bug 1550371] Re: Webbrowser slow scroll and artifact rendering on freiza

The main reason Oxide is slow is because the browser's UI thread is being blocked for long periods of time due to an issue *outside* of Oxide. As a quick test, I just ran the address book app with QSG_RENDER_TIMING=1, and it demonstrates exactly the same issue as the browser - the render thread

Oxide only runs on Ubuntu. But that's still a valid question : if that GPU was to expose such a slowdown on another OS (Android say), the upstream Blink code would probably have marked it with a quirk or blacklist to signal the bad performance of the driver. So either we end up calling

Until this is a repro written only in C linking the OpenGLES & EGL libraries (and glibc or bionic), no gpu vendor will take it very seriously. No-one appears to have addressed my comment in #18 - why does oxide not see this when it meets this GPU on other OS platforms? -- You received this bug

I agree with Chris' assessment. eglSwapBuffers blocking for so long (over 32ms, i.e. 2 frames at 60Hz) is causing Qt's main loop to block, compounding the stutter. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to
