Dear Maintainer,

I recenly upgraded mesa-vulkan-drivers via apt-get -t testing dist-upgrade to
25.3.2-2 (from 25.2.8-2, I think). In the game warzone2100 (version
4.5.5deb-1+b1) I since see a flickering black area in the top fifth of the
screen. This already happens in the start menu. It happens both using the
internal screen of my laptop and when using an external screen connected via
HDMI. lspi shows my graphics card as: 03:00.0 Display controller: Advanced
Micro Devices, Inc. [AMD/ATI] Navi 14 [Radeon RX 5500/5500M / Pro 5500M] (rev
c1)

There is a workaround, to be able to play warzone2100 again: changing the
renderer in the warzone2100 options form "Vulkan" to "OpenGL".
