At same time is happening in many cases that fonts are not readable anymore and pictures have some glitches... for example this page for me looks like this (attachment) ... and problem persist until computer freeze... if i restart everything is normal again... in log files is nothing special about this problem... but i have to admit that computer is barely usable with this problem because you never know when it will freeze and when fonts will get unreadable again...
what can we do about it?
