Normal mode mouse pointer movement creates wobble effect

[jetpilot]

(upgraded to new Hardware recently, included a Win10 to Win11 update and VB 7.0.x to 7.1.6 update. due to a higher display resolution now i had to turn on host desktop/font scaling for convenience of reading the UI element.)

now, when moving the client mouse pointer (when i have locked my HID devices to client) then moving the mouse over e.g. a console/terminal with some text written there, i am getting a noticeable wobble effect as if the mouse pointer Software emulation had problems. namely getting/restoring the pixels from/to the needed position has some issues.

looked a bit closer and found wobbling as well for just updating the screen due to keyboard interaction, e.g. it might have been scrolling.

the VGA emulation module used was set to VMSVGA.

this next block might help you in understanding when the problem is there and when not: when increasing its memory from the default (15-16MB?) to 64B then it seems like i suddenly was migrated to mouse cursor realization via host hardware support. and the described effect was gone from the client system.
