I just had to use the serial console on my APU2D (with the Tumbleweed-based openSUSE MicroOS) to rollback to an earlier snapshot in GRUB2.
And the GRUB2 menu was incredibly slow. Selecting items in the list took like 20s after pressing the DOWN_ARROW key for the selection to actually move.
Is that a known regression? I did not notice that on this machine before. Funnily, I checked another machine also running MicroOS and there the GRUB2 menu was "normal", without visible delay.
As a side note, the slow machine failed on my several times during the selection and rebooted (or restarted grub2?), so I had to restart from the beginning again...
This was the error shown directly before rebooting: error: ../../grub-core/video/bitmap_scale.c:41:null src bitmap in grub_video_bitmap_create_scaled
Is anyone aware of an existing bug report that I missed in my search? If not, worth opening a bug?
Kind Regards, Johannes
