--- Comment #16 from miklos <mtm...@gmail.com> --- How can I reopen this? Using a hint supplied by the application is clearly wrong, because application developers can't be bothered to set window properties correctly. It's especially weird that KWin developers insist on using obscure window hints here, and at the same time they lament in their blog about applications incorrectly setting their window type: https://blog.martin-graesslin.com/blog/2016/07/multi-screen-woes-in-plasma-5-7/ Some examples to illustrate the problem: Portal and GMod don't set set the block compositor hint, but Scummvm does. It should be the opposite. ETQW doesn't allow alt-tab, so I don't know if it disables the compositor (I guess it doesn't). Moreover, when a game is running, but it's minimized, then it doesn't draw anything, so it shouldn't affect the compositor, but as long as that window exists, the compositor is turned off. I don't understand why the good old "if fullscreen window: turn off compositor" logic had to be replaced with this mess. -- You are receiving this mail because: You are watching all bug changes.
