After installed Lightning 0.7, when change the theme, the performance is really slow. 

Steps:

2. Change the theme, for example, change from 'Blueprint' to 'Crux'
3. Disable Lightning 0.7 
4. Do step 2 

Result: 
After step 2: It takes more than 30 seconds to switch between themes. 
After step 4: It only take 3 seconds to switch themes. 

This bug is happened on both Solaris and Linux platform.

Switching themes probably forces Lightning to refresh and redisplay the calendar view. Dependent on your calendar type and size this might take some time. Do you notice the same delay when just switching the calendar views resp. reloading the calendar?

If just reload calendar, switch between different calendar view, no performance issue.

Emily Chen, does the issue still exists using Lightning 0.8 or a recent Lightning 0.9pre nightly test build?

Comment 4

Hi Stefan Sitter, I have tried Lightning 0.8 on TB 2.0.0.14, still have the delay issue. 

Switch from 'Blueprint' to 'Crux' with Lightning enabled, will use 15 seconds;
Switch from 'Blueprint' to 'Crux' with Lightning disabled, will use 2 seconds.

I will try to find and take a look at Lightning 0.9pre build later.

Hey, this bug seems gone on TB 3.0 + Lightning 1.0 pre. Change to WFM.
