Editor Freezes on Horizontal Scroll

[ArthurZ]

I am on 1.215.0.0 on Win 10 Pro, when editing a file that has very wide lines (reaching beyond being visible on screen) once I touch the horizontal scroll bar CT freezes. I need then to use the Task Manager to kill it and reopen. This issue started in a pre-1.215.0.0 version but unsure in which anymore.

• Can you post here (as a zip file) the example file, so that I open this file, do the horz-scroll, and see the freeze?
• do you see it on clean app (no additional plugins/settings)?

I tested on such file:

wwwwwwwwwwwwwwwwwwwwwwww eeeeeeeeeeeeeeeeeeeeeeeeeeeeeee fffffffffffffffffffffffffffffffffffff ffffffffffffffffffffffffffffffffffff fffffffffffffffffffffffffffffffffff ffffffffffffffffffffffffffffffffffffffffffff ffffffffffffffffffffffff

@miroslavmatas Hi, do you see the freeze here?

[MiroslavMatas]

tested on this file - https://www.learningcontainer.com/sample-text-file/, 2mb text file - "sample-2mb-text-file.txt" checked on my Win11 and also on Win10… no problems here verified on my configuration + on clean setup (1.215, and 1.214.7) horizontal scroll bar works fine, and no freeze, or something suspicious

Thanks for checking... maybe it is false report. I dont recall that we had changes in scrollbar code in last times.

question for @ArthurZ : change of scrollbar to OS-themed scrollbar affects it? this option:
