Hi guys.
Just to let you know - all the kernels I tried, x.5 tin x.7 , kill the system... .. when some video in a browser - as I do not playback any videos allow cannot comment there - is played or paused and some resizing or switching or showing thumbnails/miniatures (tabs) is show/played/takes place, then Fedora starts blinking my both monitors, laptop's builtin & external Dell. Blinking slow, black & desktop view alternately, at ~1 sec intervals then about ~1 min later both monitors switch black & stay that way. From the very blink system is irresponsible - hard power-cycle is a must. Interestingly(?) audio continues - until of course, all goes black - to playback okey.
Nothing else is from koji/test, up to date from repos OS. System - Thinkpad e14 g2 (AMD)
regards, L.
an update - actually.. it, no video playback at all an this issue can occur.
Does this only occur with firefox? Have you tried another browser? Chromium, seamonkey, netsurf, falkon, midori, epiphany, otter-browser, and others are available as packages in Fedora. You could also try with the alpha version of firefox called nightly, from here, in case it is a bug that has been fixed:

Does it occur with older kernels? That is, is it possibly a memory problem, maybe seating of components, or heat?
