Hello,
I have a major speed issue with koreader. My device is Kobo libra.
Here is the description :
If changing pages with full test, speed is ok, less than a second.
But if the next page include an image, not even a big photo, juste a small web image, the speed slow down. About 5-6 seconds.

I remembered that koreader was not so slow in the past. As I don't read comics, I didn't really notice it directly. But now there it became really unbearable to me, even for the few images that appear. So I decided to find out since when it appeared:

v2020.01 : OK
v2020.06 : OK
v2020.08 : OK
v2020.08.1 : not OK
v2021.01.1 : not OK
v2020.09 : not OK
And all latest releases : not OK (I download the latest nightly release about every month)

The bug seems to be appeared since v2020.08.1.

There have been a lot of new features since this release. Do you think it will be difficult to find the specific feature that caused this issue and fix it, (or disable it) ?
I hope we will not be forced to choose beetween speed and features.
For now, i decided to downgrade to v2020.08.
I am ready for testing on my device.
Thanks for your help and thanks for reading.
