Hi, I am not sure if this applies to you but, I am using DCS via steam and I have found that launching from the bin-mt folder does not make a difference when installed via steam. For Steam installation, Instead, I had to modify my desktop shortcut to force MT mode. steam://launch/223750/option1 For this issue, have you checked your bindings?

I checked this with Single Thread (ST) today and the issue is still there. I can also confirm that using Multi Thread (MT) fixes the issue. I created this post for people who are unsure what version of DCS they are running.

Writing this comment for the next time I have an issue. Hopefully it helps someone else too. How to check whether you are running ST or MT: Once running the ST icon looks like this. and the bottom right of the home screen says Version: 2.9.X.XXXXX Compared to Once running the MT icon looks like this. and the bottom right of the home screen will actually say MULTI THREAD PREVIEW 2.9.X.XXXXX Another method is that you can view the log at %userprofile%\Saved Games\DCS\Logs\dcs.log This is what confirms it. ST INFO APP (Main): Command line: C:\Steam\steamapps\common\DCSWorld\bin\DCS.exe INFO APP (Main): DCS/2.9.7.59263 (x86_64; Windows NT 10.0.22631) MT INFO APP (Main): Command line: C:\Steam\steamapps\common\DCSWorld\bin-mt\DCS.exe INFO APP (Main): DCS/2.9.7.59263 (x86_64; MT; Windows NT 10.0.22631)

I solved my own issue. It was Steam launching DCS in ST even though I specifically set Steam to use MT. Where I went wrong was that I created a desktop shortcut without realising that the desktop shortcut ignores the MT preference I set inside Steam. I followed this guide and that fixed my issue.

I also have gui offset issue raised here (issue only happens in Single Thread (ST) mode) I also have the f10 map issue shown here (issue only happens in Single Thread (ST) mode) issue goes away when i am actually using Multi Thread (MT) mode.

Edit: I discovered that I was running ST instead of MT. I fixed my desktop shortcut to use MT and the problem is now fixed. Original issue: I have a single ultrawide monitor with a resolution of 5120 x 1440 pixels and an aspect ratio of 32:9. Prior to updating to 2.9.7.59263 I was using the following LUA file to center and limit the dimensions of GUI to only 3/5 (3072 pixels) of the 5120 pixel screen which worked fine. _ = function(p) return p; end; name = _('1 Screen - del13r'); Description = 'One monitor configuration' Viewports = { Center = { x = 0; y = 0; width = screen.width; height = screen.height; viewDx = 0; viewDy = 0; aspect = screen.aspect; } } GUI = { x = (screen.width / 5); y = 0; width = ((screen.width / 5) * 3); height = screen.height; } UIMainView = GUI GU_MAIN_VIEWPORT = Viewports.Center Here is what it used to look like before 2.9.7.59263 Here is currently what that configuration erroneously displays just the background of the gui with no icons and only spanning across 2/5 instead of the intended 3/5. Again, this was not an issue before 2.9.7.59263 When I change just 1 value of the GUI section offset to x = 0; the problem goes away, i get the correct 3/5 width, but i lose my centering which is regrettable. So then I thought I would try a smaller GUI secion offset of x = 50; and we can see the GUI and icons start to glitch. I am providing this information in a hope that someone can fix this in the next patch by restoring the functionality.

You are correct, that was super confusing considering I was going into the bin-mt folder and launching the exe file from there. I am now choosing MT Preview in Steam and it works. Thanks for that!
