I am finding that both Firefox and Thunderbird (on Ubuntu 9.04) are becoming increasingly difficult to work with. Please look at the screenshots that are attached. You will see that many of the icons on the menu bars are obscured by grey bars.
Often lines of text are missing but re-appear if I scroll up and down. I have seen similar reports and have tried "zoom text only" and gone to Preferences, appearance, fonts, details, hinting full to no effect. It seems to be getting worse. Certainly during any session more grey bits appear and the text becomes more corrupt but also it seems to be worse day by day. I took Screenshot 1 about 10 minutes ago and screenshot 2 1 minute ago.
Any help will greatly appreciated
