Mouse pointer position wrong with dual 4K screens that have different scaling #56951

Open zoltanszecsei opened 8 months ago

zoltanszecsei commented 8 months ago

What is the bug or the crash?

Mouseclick activates at a position different from where the pointer is visible on the screen

Steps to reproduce the issue

Set up a dualscreen (extended mode) windows 11 system (in my case 4K 17" laptop with a 4K 28" monitor via HDMI) Set laptop screen to 150% scaling and 28" monitor to 125% scaling. Fire up QGIS and load (say) 4-5 maps - move to 28" monitor. Clicking between the maps works fine. Leave kyb/mouse/ untouched for 5-10 minutes When you now click on a map in the layer panel, it activates a map higher in the layer list.

To fix, simply drag the QGIS window to and back from the Laptop monitor - and everything works fine until you leave the system idle for "a time".

Additional context

Could this be related to #53898 ??

I am not sure why it needs some "quiet time" before the mouse pointer is affected. I have all power saving setting: Screen & Sleep: 10 mins on Battery, never when plugged in. Power mode: Full performance Battery Saver turn on at 30% - but I always use it plugged in.

I alterantely use a Dell 27" monitor at home and an AOC 28" iat the office. Same thing happens with both monitors.

This is probably related to this issue: https://github.com/qgis/QGIS/issues/54116

@nyalldawson @nirvn I suspect that QGIS canvas cursor is not high DPI aware but I am not familiar with this part of the code.

I met the same issue. When the device is not active and turns off the screen, after login in QGIS the mouse pointer get some offset with my 4K 32'' monitor. Dragging it to the laptop screen and then back will resolve it.
