So this is a problem I originally posted in Aslain's forums (because I thought it's because of the modpack).
After some investigation there was a conclusion that XVM is actually causing the underlying problem.
The problem:
Text is not displayed correctly and is hardly readable.
Examples: Ingame , How it actually looks How it shoud look
Now a user there suggested that the Compatibility for WorldOfTanks.exe is set with the "Disable display scaling on high DPI settings". And indeed it was.
However, whenever I remove it and start the game, it was reappearing. And that only happened when there were mods installed.
So with the method of exclusion I singled XVM as the culprit.
Video proof (2:02 min)
(Explanation of timeline in the video description, if needed)
Attached python and xvm logs from the video.
Problem appeared with patch 0.9.20.1.1 (Halloween patch)
P.S. If it's not obvious, I am looking into how to stop that behaviour so I can have the text in the client displayed properly.
python.log
xvm.log
