ddraw:ddraw1, ddraw:ddraw4 & ddraw:ddraw7 - test_coop_level_mode_set_multi()
sometimes gets unexpected screen width on GitLab CI Wine:

ddraw7.c:3976: Test failed: Got unexpected screen width 640.
ddraw7.c:3978: Test failed: Got unexpected screen height 480.
ddraw7.c:4011: Test failed: Got unexpected screen width 640.
ddraw7.c:4013: Test failed: Got unexpected screen height 480.
ddraw7.c:4034: Test failed: Got unexpected screen width 640.
ddraw7.c:4036: Test failed: Got unexpected screen height 480.
ddraw7.c:4041: Test failed: Got unexpected screen width 640.
ddraw7.c:4043: Test failed: Got unexpected screen height 480.

The bad screen width may also be 800,

There is typically no prior test failure. In the past four months it has
happened exclusively on the gitlab-debian-*:

* 2023-08-16 MR!3577 ddraw1
* 2023-07/28 MR!3435 ddraw4

* 2023-04-21 MR!2659 ddraw1
* 2022-12-07 MR!1705 ddraw7

This also happened on other platforms but these days it seems to only be Linux:

* 2023-01-30 linux_fgtb-debian11-wow64

* 2023-04-07 win21H1_newtb-w10pro64-ar-64
* (2023-05-10..12 w1121H2_newtb-w11pro64-amd-64 likely windows update trouble)
* 2023-05-23 linux_fgtb-debian11-wow64

* 2023-07-20 linux_fgtb-debian11-wow64

And this also happens frequently on Remi's Linux machines.
