@jimmyrogue Could you provide test case code, similar to codesandbox?

jimmyrogue commented 7 months ago

@mfuu here: case

funny thing is you must open web dev tool(F12) and the bug will show

I think some css trigger this bug

mfuu commented 7 months ago

@jimmyrogue It's caused by the size change of the image before and after loading.

@mfuu thanks but if I still need to calc the height of image by a function or dynamic, how to do it correctly ?

mfuu commented 7 months ago

@jimmyrogue I am trying to solve it, you can re-open the issue if you want

mfuu commented 7 months ago

@jimmyrogue Try to pass an estimated size with size prop, like:

<virtual-list :size="50"></virtual-list>

@mfuu thanks and I find if I calc the height earlier the problem will solve
