I have had this CPU for 8 months. I have had issues from day 1 with the stock Fedora install of Firefox where text is missing and some green and/or pink boxes appear where the text boxes should be. This has happened with all versions up to 129.0.

This has only been happening with Firefox. Vscodium, (chrome based) Brave and every other Wayland application including foot and freecad render correctly. it is only firefox and only firefox with this GPU. If I run Firefox under qemu without eGL then the rendering is good. If I run it under qemu and enable the virtioGL driver I get the same issue.

I attach a sample of a screen shot that shows that was captured from the frame buffer. In the bottom left corner, you can see quite a few characters missing. This happens randomly and sometimes goes away when scrolling.

I have seen other issues that say that it is a hardware problem, but I am not convinced. This happened with mesa-24.2.0. Find the glewinfo attached below: (Glewinfo log is very long, uploaded to Pastebin for better viewing) https://pastebin.com/raw/1NMnAjmc

I'm not able to replicate the issue. see screenshot Have you tried a different Desktop and X11? Did you try with Firefox in Troubleshoot Mode? Try downloading Firefox from Mozilla. Download, unzip, and run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

Which nvidia card and driver version?'

I have tried using --safe-mode and I was unable to reproduce the issue. Using only weston as the windows manager the issue still appears. You can see that from the screen shot. Using a fedora boot USB has the same issue. You can see this with the characters incorrectly rendered.

This only happens with this GPU (the on die one). I added an old video card and the problem doesn't happen when using that video card AMD RX480 (same kernel driver, different mesa):

Please note, it wasn't clear but the rendering sometimes resolves itself on a redraw, eg via scrolling. I have read other posts about as similar problem on reddit but I don't believe that this is a hardware problem. Unfortunately, I have been waiting 8 months with several version of mesa, kernels and firefox and the problem that on intermittently appears with firefox and only firefox (not other apps) hasn't been resolved.

Kernel version 6.10.6

I was going to mention Graphics and driver version.

You can check for issues with fonts.

You can right-click and select "Inspect" to open the built-in Inspector with this element selected.

You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Fonts tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website, if necessary expand "All fonts..."#. If the Fonts tab is hidden, click the Down arrow at the right end.

Are you saying that I don't have the fonts that kernel.org is using? But then again aren't there rules that enable a suitable substitute to be found. eg sans or serif, etc?

I can reproduce this with a fresh fedora install USB boot. The problem is intermittent. The problem is transient, a glitch, that can often be remedied by redrawing the page in the framebuffer. As the screenshot picks up the incorrect rendering then, in my opinion there is nothing wrong with the framebuffer memory. This only happens with the this particular video driver. The same problem appears even when running with emulation, ie. making graphics calls from virtio_gpu, but not using virtio_qxl for instance.

Does this still happen if you disable hardware acceleration in Firefox?

Close and restart Firefox after modifying the setting to apply changes.

If you disable hardware acceleration then the issue doesn't appear (after about 5 minutes). If you enable hardware acceleration then the issue does appear after the first or second page with text.
