I haven't seen this one yet, but I only got about half way through the massive bug list thread.
Product: Kobo Aura H20
Firmware: 3.18.0
Plugins: None
File types: PDF
Sideloaded or from Kobobooks: Sideloaded I guess.
On external SD: No
Steps to reproduce:
- Open Pdf
- Zoom Pdf
- Pan, it pans normally
- Sleep the device with the power button
- Wake up the device, with the same power button
- Pan
- Get strobe light panning
Current result: Device flickers black and white while you're panning, which is not the normal pan behavior
Workaround: Go back to main menu, reopen pdf, zoom in and pan normally. Pretty much don't let the device go to sleep while a pdf is open. Kind of kills the sleep feature.
