@Aron, could you please give a try to this issue?
Hi Telesto, Is this issue still reproducible in master ?
I can more or less confirm with 6.2 beta1 / Windows 7. Perhaps it doesn't take 5 seconds to open at first, only 2-3s but scrolling around is definitely slow, and doing that and closing/reopening the file a few times slows things down to 5s level, which is interesting.
As Skia with Vulkan will replace OpenGL UI rendering on all platforms, it does not make sense to keep OpenGL UI reports open. Details about Skia: https://www.collaboraoffice.com/success-story/implementing-vulkan-capable-libreoffice-user-interface-using-the-skia-library/
