--- Comment #8 from sashok724 <bugs...@sashok724.net> --- I think i figured out a solution for this problem. I just replaced this line in QuickEditor.cpp(625): resize(mScreensRect.width(), mScreensRect.height()); with: resize(qRound(mScreensRect.width() / devicePixelRatio), qRound(mScreensRect.height() / devicePixelRatio)); So region selector window is created with correct size. But, it was not the only problem. In region selector, leftmost screen contents was duplicated to central screen. I fixed it by also removing this line from QuickEditor.cpp(662), as width and height of rect appears to be already scaled, unlike X and Y, i do not know why: rectToDraw.setSize(rectToDraw.size() * devicePixelRatio); If what i done is correct solution, i can create pull request. -- You are receiving this mail because: You are watching all bug changes.
