--- Comment #3 from pemartins <paulo76.alga...@hotmail.com> --- I was able to fix this by installing flash player in a different way. At first flash was installed as sudo apt install flashplugin-installer but for some reason the crash happened every time even after reinstall. But installing flash as sudo apt install adobe-flashplugin browser-plugin-freshplayer-pepperflash solves the issue and flash video in full screen mode no longer crashes plasmashell or KWin. -- You are receiving this mail because: You are watching all bug changes.
