We're slowly working through the entire UI to replace it with newer stuff. The TM:PE v11 LABS page is where we're testing those updates if you want to see if improves things (remember to unsibscribe TM:PE v11 STABLE first though; due to game limitation only one TM:PE mod can be _subscribed_ at a time otherwise you get settings loss).

Out of curiosity, what screen resolution are you using (and what aspect ratio)?

Thx for your fast and kind reply!

Changing from STABLE to LABS didn't solve the problem. Later today I'll deactivate all of my other mods to see if the problem results from any incompatibility with one of them.

And cause of your curiosity: My screen resolution is 3840x2160 and the aspect ratio is 16:9.

If disabling other mods fixes it, please let us have a list of those mods and hopefully we can track down the problem (or at least point people to the list so they know which mods to try disabling).

v11.5.0 will be released in few days which will hopefully solve any issues with the main TMPE toolbar and lane arrows UI. I think speed limits is next on the list (likely v11.6.0) and then at some point traffic lights (probably 11.7.0 or later as it's most complex bit of UI in the mod).

Also, check the scaling slider in TM:PE mod options screen on the General tab. Each upgraded bit of the UI will respect the setting of that slider.

Okay, the problem is made by the game itself: My very own screen resolution is in fact 3840x2160. And so have been the ingame-settings. I just chose another resolution INGAME (!), just one step smaller, and a wonder happened: The game itself does not lower the resolution, but some ingame-window-sizes changed. And so did those little windows of your TM:PE-LABS! :-D

So just to clarify: To solve the problem of small ingame-windows in C:S you just have to lower the resolution INSIDE THE GAME at least one step. (settings > graphics > resolution)

And for your interest, @aubergine18: There has been no incompatibility issues with other mods. I tested that first before I found out this simple solution. ':-D
