I installed secureblue on my Framework 13 recently (HX 370 with Radeon 890M iGPU) and noticed glitching when mousing over text in text-heavy websites. I've observed this happening in Trivalent, Brave, and Firefox, so I don't think it's a bug in Trivalent specifically. Could it be a GPU driver bug? Are people seeing this on base Fedora Silverblue?
See attached video for an example of the glitching.

I'm running secureblue on a Framework 13 AMD (though it's a 7040 series so slightly older CPU and iGPU model), and I've never seen graphical glitches like that in any browser
might be worth asking on the Framework community forum
it does look like the visual glitches extend to the top bar, not just within the browser window, so it makes me think it might be a hardware issue independent of the browser... like could it be a loose cable or something? did you assemble it yourself or buy it preassembled?

doesn't look like the browser itself since the flicker is occurring on the whole screen

Update: I booted into Ubuntu 25.04 off a USB drive, which uses Mesa 25.0 and Linux 6.14 (same as secureblue/fedora silverblue), and got the same glitching on the same page.
I then tried Debian 13/testing, which uses Mesa 25.0 and Linux 6.12, with the same browser and page (Firefox in all cases) and the glitching did not occur.
So the problem seems to be in Linux 6.14, most likely the amdgpu driver. It also seems likely the problem was introduced in Linux 6.13, though of course I don't have evidence since I didn't test using a distro with 6.13.
I'll file a bug report against amdgpu on freedesktop.

amdgpu driver moment

I've had weird graphical glitches come and go with amdgpu before. That driver has a weird amount of instability and churn for some reason. Linux 6.10-6.12 (prior to 6.12 stabilizing as LTS) was especially bad.
the funny thing is, at least anecdotally, the driver seems to have gotten less stable over time...

But it has AI™

I don't think the driver has any "AI" garbage in it, does it? it's just AMD's marketing term for their latest generation of hardware
