[PinePhone] Program will only display garbage after zooming in or out #54
Description
The zoom feature is broken in Image Roll v.2.1.0 on postmarketOS v.22.12.2 running on a PinePhone.
Opening images, switching between them and rotating them work fine, however as soon as you press the "-" or "+" button, the display becomes corrupt (no picture is displayed anymore, only black or white rectangles, sometimes mixed with UI elements showing up at wrong places) and other features don't work anymore: the menu opens as a black rectangle and reverting to the "fit screen" mode and/or switching to the next or previous image doesn't bring a picture back to the display. Only a restart of the program will restore its functionality.
