Created attachment 120797 [details] screen capture of LibreOffice Writer document after scrolling After a push notification from Toshiba to update the display adapter driver (Intel HD Graphics 520) to version 20.19.15.4300 on my Toshiba Satellite laptop running Windows 10, I found that after opening an existing Writer or Calc document, the screen blackens when scrolling up and down. It remains that way until the program is minimized and reopened, but it immediately blackens again upon scrolling. None of the other programs on my laptop have been affected by this.
Thanks for reporting. Please test is enable/disable OpenGL in Menu/Tools/Options/LibreOffice/View - Graphics output, has any effect.
Please answer here if you can. " Tested the suggested fix provided below but it didn't work. However, I rolled back the display adapter driver to the previous version (10.18.15.4281) and the problem has completely vanished. So the issue is clearly related to the newer driver. " Let's as unconfirmed, maybe someone with the same hardware can test.
