- Can someone please advise where I send a Request for Support to Metaquotes. - MQL4 forum
- Get in touch with developers using Service Desk! - MQL5 forum
- Report it to the service desk. 'MQL5.community - User Memo' - an article about the algorithmic/automated trading in MetaTrader
- Report it to the Service Desk, not us users.
If the "arrows/lines/etc." are drawn by custom indicators / scripts / EAs, you may find the problem is with their coding rather than a bug in MT4. A screenshot might help.

In MT 4 (1031 Build) the scaling of symbols (arrows, lines, etc.) does not correctly work when Windows 10 DPI/Screen scaling is enabled.
