After update from 6.0.4 to 6.0.8 (or 6.0.6) the mouse position was incorrect after changing screen resolution.
Host: Windows 10
Guest: Linux Mint 19.1 Xfce 64 Bit (guest additions correspond always to VB version)
Graphics controller: VMSVGA
After boot everything is correct:

I dragged the mouse on the desktop. So a rectangle shows the current mouse position (correctly at bottom right corner of the rectangle) (you have to scroll down the image)
Now i switched from full screen to window-mode (<host-key>F). Now the rectangle is far away from the mouse position:

Switching back to the "original" screen resolution shows the correct mouse pointer postion again
If i reboot the guest in window mode everything is correct again. When i switch to full screen, the guest desktop becomes weird:

The task bar is enlarged (note the enlarged green whisker menu entry). Unfortunately, the current mouse position is not shown in the screenshot. It is far away from the highlighted menu entry "Thunderbird Email".
I did not change anything in my system with the exception of the VB upgrade.
Upgrading Windows to May, 17, 2019 brought no improvements, same after updating mint
Switching to VB 6.0.6 did not change anything.
Going to version Build 130207 (recommended by michael) is not possible because this version is no longer available.
Downgrade back to VB 6.0.4 didnĀ“t change anything either (incl. downgrade of guest additions of course). There is also something strange with the re-installation of 6.0.4: windows does not ask for the re-installation of the network-adapters (Netzwerkapter in German). I assume, i am working with parts of 6.0.8 or 6.0.6 after downgrading to 6.0.4
I managed to find a way to change the screen resolution without rebooting: if i log out from linux (In German: "Abmelden"; <ctrl><alt><backspace>) i can switch from full screen to windowed mode (<host>F). When i log in again, everything is correct.
Another strange thing: the linux task manager lists double entrys for "VBoxClient --clipboard", "VBoxClient --display", "VBoxClient --draganddrop" and "VBoxClient --seamless". i don't know if this is correct, because i have no choice to compare that with a working version of VB.
I also tried the following:
- changing VB mouse setting from tablet to ps/2: no change
- changing mouse capture (<host>I): no change
- using old kernel in Mint (4.15.0.48 instead of 4.15.0.50): no change
- guest Windows2000: everything works correctly
I can provide appropriate log files for 6.0.8 and 6.0.4 (after downgrade).
Any help very appreciated!!
