Bug ID: 50982
           Summary: Mouse clicks are sometimes offset higher (~20 px) than
                    the mouse cursor in LTSpice, winecfg and explorer
           Product: Wine
           Version: 6.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

winecfg output during prefix creation and automatic wine-mono download
Mouse interactions are sometimes offset 10~30 (random) pixels up from where the
cursor is displayed
Tried in LTSpice XVII and in winecfg, with wine 6.6 (Arch Linux "wine" package,
wine-mono downloaded by wine and not from the Arch package) in a new win64
Windows 7 prefix.
Wine 6.5 worked fine.
I cannot test with the latest developement version for disk space and available
time problems.
## LTSpice XVII
LTSpice is a light and easy-to-use electronic simulation freeware by Analog
Devices:
https://ltspice.analog.com/software/LTspiceXVII.exe
(Installation log attached, using app defaults)
(Run log attached)
In the component selector: open an existing schematic and right click on a
transistor, or create a new schematic and add a transistor (F2, select "npn",
Enter, place it anywhere with a left click, then Escape) and right click on it,
try to click on new transistor, try to select any of the parts.
In the component selection window, in the Bipolar Transistor right-click menu,
in the transistor selection dialog and also in the save modified file prompt
when exiting, I need to point a bit under the button or item (0~30 pixels,
variable) to actually click on the item and not on whatever is immediately over
it.
Sometimes the offset varies in the same window, for example from about 20
pixels to zero.
I did not find that the toolbar, the menu bar or the schematic view were
affected.
The list of transistor types in the transistor selection dialog also has
another problem: the grey header of the list, with labels such as "Part No.",
"Manufacturer", Polarity", "Vceo[V]", is often drawn blank or with an
incoherent line of the list, and reappears only when scrolling right. This is
mentioned to ease usage of the application, ideally I should file another bug
for this issue, but I haven't done it in the past three years.
## winecfg
While creating the clean prefix (by running winecfg, see also attached log), I
found that mouse clicks are also offset in winecfg, for example when adding a
drive unit (pointing to a folder), the drop-down menu that allows one to select
a drive unit also rolls down only if I click about 20 pixels under its lower
margin, and the same for the OK and Cancel buttons.
The Add button and the other controls in the winecfg tab do not behave offset.
## explorer
The file properties popup has the same offset problem.
It seems to me that the issue manifests itself in popups.
Performing enough clicks and resizes on the window, sometimes the offset goes
away.
