I know this behaviour from 1.2.1 and 1.3b, but not from 1.3a. Reproducible: Always Steps to Reproduce: 1.load *this* page 2.load e.g. www.google.de 3.move the mouse while pressing Alt-Tab *or* 2.load a page which needs a long time to load 3.move the mouse
1.3 final on Linux does not behave like this, 1.3 final on Win2K does
I found the solution. Fasten your seat belts. ;-) My PC's power supply is too weak, and that made Mozilla slow. Only Mozilla, not IE, not Winamp, no other program. No joke. I changed the graphics card from NV TNT to MGA G100 (which consumes less power), I wanted to check what lets my PC freeze occasionally since I changed the motherboard last week. Result: Mozilla 1.3 works fine, no mouse movement or Alt-Tabbing lags, and the PC is stable since then... before the board change, the problem was there also, but with the old board the PC was stable. I can only guess that Linux configures the machine for less power consumption than Windows, so the problem did not occur there. It *could* be a graphics driver issue of course since I used the NV in the old board also. I will check 1.3/Win32 at work tomorrow (graphics card is ATI 128CF), but I guess it will work fine there. If it works, I could install my NV card there to see if the problem is related to the NVidia driver; when I see the problem there also, I'll reopen this bug with a summary "Mozilla slow on NVidia graphics cards" or something similar.
