Instead, you may want to see the workaround provided in the Intel driver wiki entry and look into providing feedback and system information to the linked FreeDesktop bug report.
]]>I can't see anything of interest in the xorg logs.
My CPU is a Core M-5Y10c with integrated HD 5300 graphics. I'm using the xf86-video-intel driver.
I'm going to try fiddling with the options listed on the wiki. It might be related to this bug: https://bugzilla.kernel.org/show_bug.cgi?id=109051

Here are some screenshots of the issue:

Rebooting fixes the issue, but that's not an ideal solution, for obvious reasons.
I have had other issues when resuming from sleep, for example once the system was completely unresponsive and I had to reboot.
Does anyone have any ideas?
Edit: I just closed and opened the lid of my laptop, to see if that made a difference. Now 99% of characters are invisible. I'm writing this completely blind. I guess I'm going to have to read any responese with elinks (My termial font seems unaffected).

Edit: Exiting to lightdm and logging back in seems to have temporarily fixed it. Is there some kind of font cache that is getting flushed? (I fixed my typos btw)
