Bug ID: 155143 Summary: LibreOffice Apps crashes when scrolling document with the mouse on 4K screen Product: LibreOffice Version: 7.5.1.2 release Hardware: x86-64 (AMD64) OS: Windows (All) Status: UNCONFIRMED Severity: normal Priority: medium Component: Writer Assignee: libreoffice-bugs@lists.freedesktop.org Reporter: marci...@gmail.com Description: The problem started when I changed the monitor to the 4K model about a year ago. I connected my old monitor as a second. I set 4K resolution on new monitor with scale 175% and the old one works with 1920x1200 with 100% scale. I worked with documents like normal. Some edit, copy, paste and when I scrolled the document the app freezes for a few seconds and then closes. All opened documents close without any question about save, so all work withut save is lost. It happens on my PC at work and at home. Both have the same configurations of monutors (4K+1920x1200). It also was reported by my friend after buying 4K monitor. He has only one monitor. Steps to Reproduce: 1. Open any document in Writer, Calc or Impress 2. Edit like always 3. Scroll document with the mouse Actual Results: When scrolling the document in Writer, Calc or Impress the whole LibreOffice crashes. Without any warning or information about crash. All LibreOffice apps and all opened documents just close. The app first freezes, then after few seconds closes. Expected Results: It shouldn't crash :( Reproducible: Sometimes User Profile Reset: Yes Additional Info: I selected Writer but the problem exists also in Calc and Impress. The same problem exists in 7.5.2.2. It happend also in some previous versions. I don't remember all tested versions. I'm sure that I tested 7.4.3 (LibreOffice_7.4.3_Win_x64.msi) and some version from 7.3 line. Some time ago I made more tests by installing old version from download archive. I found that verion 7.2.6 (LibreOffice_7.2.6_Win_x64.msi) works properly without crashes. I send this information to my friend and he also uses this version without problems. I also noticed that 7.2.6 works stable after the uninstalling the previous one and installing this one then. When I installed 7.2.6 over the 7.4.3 it was no stable. About a month ago I decided to test the new version (7.5.1.2) and the problem returned. After first crash I deinstalled LibreOffice. Then deleted user profile in Windows. And installed 7.5.1.2 again. Today after crash I decided to write this bug report. If I can help with search of source of this bug generating some log/dump files please let me know how to do it. About the system: As I wrote all configurations with 4K monitors. Also all with Windows 10 Polish. All with NVIDIA graphics. The last words: Few minutes ago I deinstalled 7.5.2.2 and installed 7.2.7.2. I opened few documents (Writer, Calc and Impress). I scrolled them all. And it seems to be stable, like the 7.2.6. -- You are receiving this mail because: You are the assignee for the bug.
