Bug ID: 424224 Summary: Accidental zoom to 1600% is untolerably slow Product: okular Version: 1.3.3 Platform: Ubuntu Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: okular-devel@kde.org Reporter: rao...@gmail.com Target Milestone: --- SUMMARY Okular 1.3.3 viewing PDF files under Ubuntu 18.04 STEPS TO REPRODUCE 1. Do something with keyboard or mouse BY ACCIDENT. I have no idea what it is; I am certainly not trying to Zoom and sometimes am trying to switch to another program. This may perhaps involve the mouse wheel, but I am not sure. Do this while viewing a book of say 100 pages or more. 2. Okular interprets this as a request to zoom to 1600%. There is no way to configure the Zoom drop box to restrict the zoom range. 3. OBSERVED RESULT Suddenly, out of the blue, the Zoom box displays 1600% and the computer locks up for several minutes. You cannot interrupt the process. I have a 2-core laptop and a 4-core laptop and on both of them the whole machine seizes up: music and videos stop playing or stutter to a stop, nothing else responds, the mouse may not track. EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Liux Ubuntu `8.04 (available in About System) KDE Plasma Version: ? KDE Frameworks Version: 5.44.0 Qt Version: 5.9.5 ADDITIONAL INFORMATION -- You are receiving this mail because: You are the assignee for the bug.
