Backspace Lag in Visual Editor under FF 4 with Win 7
|Reported by:||macmanx||Owned by:||azaozz|
Two of our users on WordPress.com have so far reported that backspacing is strangely slow in the Visual editor when using Firefox 4.0.1 while hardware acceleration is active.
Both users are running Windows 7, but with different hardware.
I was unable to duplicate the problem under Windows Vista, so this looks like it's specific to just Windows 7. Co-worker Veselin Nikolov noticed a 16 millisecond lag when backspacing on his rather powerful Windows 7 machine, which could certainly magnify itself on much slower PCs.
He tested again on a self-hosted 3.1.3 blog and noticed a 12 millisecond lag, so this appears to definitely be related to TinyMCE, though I suppose it could also be a bug with Firefox 4 running under Windows 7.
To reproduce, type something the Visual editor via Firefox 4 under Windows 7 with hardware acceleration active, and start backspacing.
