Holding down the left mouse button when selecting around shapes or objects used to show a line encompassing what was being selected, but it seems to have disappeared ?
Have you recently had a windows update, that often loads poor drivers for the intel graphic card. You can check for an updated driver from intel, not windows.
If it’s not that you can try turning on or off ‘Use Fast feedback’ in Window/Preferences/OpenGL
i just tried turning on / off use fast feedback and my graphics card says already latest drivers are installed. I have just noticed in preferences there is an option says component /group highlighting has a tick box “bounding box only” which i guess it what i need, but with or without the tick makes no difference. I’ve tried restarting the device but still the same.
