Getting all sorts of text artifacts remaining smeared across my browser. Not this site's fault, and is something I've experienced before. It does make me wonder where the blame lies, though: Linux, Firefox or my graphics card?



The most likely would be Firefox. As Linux has nothing to do with graphics, so I assume you mean your X Server - like Gnome or XFCE or KDE - none of which have much affect into major browsers, which are designed to render themselves entirely separate from the system's window manager to be multi-platform. It's also not likely to be your graphics card, otherwise it would happen outside of your browser too. It could be the browser attempting to "accelerate" web pages by using your GPU - in which case you can find out by disabling GPU Accelerated Rendering - both Firefox and Chrome have settings for this.

Sorry, I should have specified better. By "Linux" I meant the overall mix of Xorg and whatever display or GUI toolkits are in use, and instead of "graphics card", I should have said "graphics card drivers". If the card itself were having issues, I'm sure more than Firefox would have problems. Alternatively, I always hear about how "Linux has bad font rendering!" but since I'm not much of a font guy, I'm not sure if they're referring to how the fonts look, or some deeper part of the process which displays the fonts.

I recently had to switch to the radeon (open source) drivers instead of fglrx (AMD's proprietary) drivers due to some incompatibility with a kernel upgrade. It makes sense that the problem would exist somewhere between Firefox and its use of those drivers.

That does sound like it could easily cause problems. Graphics drivers are bad in all Linux systems. NVIDIA's I've seen tend to work better - just hope Steam does well with Linux and pushes ATI to finally make some good drivers.

-----


I believe your last guess is correct, in which case the fault is with the graphics card drivers.

-----


My priors would be: if it's an ATI card it's their fault, otherwise probably firefox.

I'm seeing trails on Chrome 23. They go away if I switch tabs and return. So it's not specific to Firefox at least.

-----


I'm curious what OS and graphics drivers you are using. I've gotten a similar effect once in a blue moon while simply scrolling.

This is Ubuntu 12.04 using the integrated graphics in the Intel i7 CPU/chipset. Never seen quite that effect before however.
