Attempts to reproduce "crash" failed after the first 2-3 attempts. This was from a "cold" LO start, one run with HW acceleration, then disable HW acceleration and run presentation again. Point being, don't rely on Impress working with HW Acceleration disabled at 4K resolutions. It may crash a few times. With HW acceleration enabled screen paint is very slow followed by a blanking/tearing of the presentation screen immediately after screen paint completes. After "crashing" behavior stopped (3-4 tries), I was able to make it through the entire presentation, with excruciatingly slow screen paint speeds. Positive comment: Once the screen is rendered, the image is beautiful. I have one animated slide in this presentation which works properly even without acceleration.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
