Edit
The glitches are back
The bios update only gave me a temporary fix.
Original :
Hi, I have encountered a weird issue with the framework 16 display.
I’ve sent a support ticket but I post here too so there is a more public record of the issue.
The internal display started showing weird ghost lines flickering periodically (for a few seconds ~ every 1 to 3 second). The artifact appeared randomly while I was watching a youtube video with a bluetooth headphone connected and no other device connected to ports, laptop not plugged in.
From then, they were visible during boot, in the bios, and in the OS.
I tried a full cold boot after waiting 15min powered off and unplugged and the glitch were still there.
Plugging in external displays was fine and I took the time to update the bios from 3.02 to 3.03. The glitch disappeared during the bios update screen after the reboot. (I saw them very quickly when booting but then the update process started and they didn’t come back)
I hope it’s nothing to worry about.
Here is what it looks like (zoom in to see the glitch) :
Have you checked the display connector on the motherboard is in properly? My replacement arrived and as I was checking it over for faults I noticed the connector for the display wasn’t fully seated. Good thing I noticed it then as stripping to fault find and rebuild can get very tedious.
I didn’t have time to check yesterday but I checked this morning and the cable is properly seated.
And now the glitch stopped after ~4min of the laptop being on. No dmesg log or journalctl entry.
So, it seems to be a very random issue, it looks a lot like a faulty component somewhere along the internal display signal route that doesn’t behave as expected under very specific circumstances (sustained load maybe, as the glitches always appeared after being on for some times and disappeared close to booting).
If anyone has an idea of any other step to debug the issue I’m all ears.
I am experiencing the same. I was working with two external monitors (via a Dell TB4 docking station) and the FW16’s screen first got corrupted (like a GPU memory bug), then displayed something static but looking okay but got dimmer and dimmer. During reboot, the ghosting was visible even in the POST screen And in Linux, the screen seems to flicker, could be corruption or brightness. Dimming from 0% to 100% works but the flickering occurs on all brightness levels.
Will write a support ticket.
New discovery: The flickering only occurs when the screen is idle/static. It does NOT flicker when I keep moving the mouse cursor (fast).
Pics or it didn’t happen: GRUB screen (bg should be pitch black) with my KDE wallpaper “burned in”:
I’ve had the same issue, but on a much worse scale. The screen just randomly glitches out all yellow and green. Sometimes it’s isolated to the taskbar and top bar for my browser (Microsoft Edge) while other times it’s the whole screen. It fizzes around like the video Q_Map provided above (but kinda worse) as it jumps in and out. Restarting usually fixes it for a bit, but often it’ll just come back not long after. I go long streteches without seeing it, then see it multiple times in a day or two.
I’ve found out that it’s an issue of the integrated graphics card (780M) as it fixes itself if I launch a game or something on the 7700S and comes back when it switches back. I saw someone suggest it’s hardware acceleration in whatever browsers that causes it, but disabling that didn’t fix it for me. My hunch is that it’s something wrong with the driver (perhaps something that hasn’t be addressed/noticed by AMD yet), but that’s about all I can figure out right now.
So, screen recording the issue shows the issue not existing, so maybe it’s a display driver issue instead? It doesn’t seem to happen when using the dedicated graphics card though… Maybe that’s just coincidence? Maybe not… Either way, gonna try and update them
The screen recorder does not actually capture the display as it is output, it captures it somewhere prior to that.
For example, I find that screen capture does the capture before ICC color profiles have been applied. Gnome ICC functionallity is broken.
What this means is that even though the screen capture looks fine, it can still be something wrong with the graphics card.
That particular output looks like only RED and GREEN are working, with no BLUE light at all.
RED+GREEN == Yellow
From that, I think it is unlikely to be the GPU. The signal between the GPU and the display is not 3 signals R,G,B it is a single signal that caries the whole image.
So the wires from the GPU to the display are OK, otherwise you would get no display at all.
A good test is to press F2 during boot up and get into the BIOS. See if the colors are OK there or not. If they are still wrong in the BIOS, the problem is most likely the display is faulty and needs replacing.
And in Linux, the screen seems to flicker, could be corruption or brightness. Dimming from 0% to 100% works but the flickering occurs on all brightness levels.
