Description: When I full screen LibreOffice Calc, Writer or Impress on my smaller screen (1280x1024) it stops working properly. It looks slightly distorted, menus show blank, I'm unable to see any changes to the document. CPU usage also goes up considerably It works well on my other two monitors (standard 1080p & 4k monitors respectively). It seems to be having issues when adjusting to this window size. Steps to Reproduce: 1. Open Libre Office Calc on 1280x1024 monitor 1a) If it opened on a different monitor: Move to 1280x1024 monitor 2. Maximize window Actual Results: Window may look distorted, CPU usage goes up and you can't use the program. Expected Results: Program should have worked normally Reproducible: Always User Profile Reset: Yes Additional Info: It was working without issues until recently. The only recent change was replacing a 1440p monitor that broke with a 4k monitor, although I can't say for sure that is when it stopped working normally. Though I suspect it might be related to adjusting between 4k monitor and a much lower resolution monitor.

Could you apply https://wiki.documentfoundation.org/QA/FirstSteps ? Specifically, it may be related with this part: https://wiki.documentfoundation.org/QA/FirstSteps#Graphics-related_issues_(_Skia_)
I've tried those steps, by default Skia is enabled and changing those settings doesn't fix the issues. The behaviour changes a bit, a lot of flickering with skia off, for example, which is not better. Also updated to 7.6.4.1 and there were no changes.

Not repro on Windows. Everything seems to be working as intended. I did just change a 1080p monitor to 1280x1024 and tested it that way.

My main monitor is 5120x1440p, which is close to 4k in the amount of pixels but not quite so I can't get a 1 for 1 representation of your setup. Since this happened after swapping monitors it might be related to that? is your 4k monitor plugged into the same "device" (graphics card or other) as the 1280 x 1024 screen? Regardless, more testers will try and see if this occurs for them :) Would you mind also providing the exact build you are using?

Some additional information, if I lower the resolution of my main monitor in the display settings to 2560x1440, everything works without issues. Makes me believe the issues is related to the way scaling is being handled between monitors with vastly different resolutions.
Version must correspond to the "earliest affected" so revert to 7.6.2.1
Was trying to get more info on what was causing the issue, by changing monitor position and scaling. And somehow the problem went away completely, even after going back to the original settings. It's been more than a week and it hasn't returned.
Thank you for the feedback, let's put this one to WFM then. Don't hesitate to reopen the tracker if you find a reliable way to reproduce this.
