Can confirm, I experienced this bug recently while trying to read books in a portrait orientation on a Steam Deck. Indeed, the absolute y offset of a document is literally preserved, so pages fly back and forth underneath your fingers while zooming. I haze this problem too , and canot zoom by pinch touch smoothly *** This bug has been marked as a duplicate of bug 421755 *** |
Created attachment 159270 [details] Video showing Zoom In/Zoom Out changes page number SUMMARY Using Pinch to Zoom with two fingers on a touch screen computer changes the page number of the document in addition to zooming. This happens for both Zooming in and Zooming out. STEPS TO REPRODUCE 1. Open a PDF/DJVU/any other document (with multiple pages) in Okular on a touch screen computer 2. Try to zoom in/zoom out using two fingers OBSERVED RESULT In addition to Zooming in/out, Okular changes the page number EXPECTED RESULT Behavior should be identical to what happens when one presses the combination "ctrl +" or "ctrl -". The document should be zoomed, but the page number should not change. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux (all updates applied) (available in About System) KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.106.0 Qt Version: 5.106.0 ADDITIONAL INFORMATION The same bug is present in Okular 21.12.3 in Ubuntu MATE 22.04 running in another touch screen laptop. I am attaching a short screen record of the behavior when I zoom in/zoom out using touch screen.
