Description: When a background image is loaded, Calc displays horizontal narrow white lines across the image. These white lines line up with the buttons on the left side of the spreadsheet. I have hardware acceleration turned on. Anti-aliasing turned off. Skia is currently disabled. If I turn Anti-aliasing on, the white lines disappear, but the response time for entering data gets very long: one to two seconds between pressing enter and having the next cell be activated. Steps to Reproduce: 1. Import a background image. 2. 3. Actual Results: The image is imported, but a number of horizontal white lines appear across the image. Expected Results: There should be no white lines.

I do not have any white lines, neither with Skia enabled nor with Skia disabled.

I have a couple of other observations. 1. I just noticed that when a new image is loaded, it is clean, that is no white lines. When I do Alt-J, which aligns the view so that the AM weather block is positioned nicely and sets the active cell to be the first data cell for the AM weather, the lines appear on the image. Because the weather block is aligned so that the top corner of the AM weather data is at the top left corner of the spreadsheet, you can't see the white lines unless you do a Ctrl-Home. 2. You will notice, just from the screen capture I sent in the Zip file, that the horizontal white lines correspond to the tops and bottoms of the buttons along the left side of the spreadsheet. 3. On occasion, the first time I do a CopyDown, Alt-], I see a quick flash of the buttons displayed, even though they are out of sight of the current view. This makes we wonder if the way the buttons are displayed has something to do with the white lines and the occasional flash of buttons.
I just went to the next day's image. After the date was set, I did a Ctrl-Home. No white lines. I moved around with arrow keys, no macros, so Cell C4 was top left in the Calc window. I entered a number in D5, did Ctrl-Home and the lines were there. While I was looking at the screen, Calc did an Auto-Save. Initially there were no white lines associated with the bottom two buttons, but they appeared after the Auto-Same. I'm not sure if this helps.
One last observation. These images are very large, about 13777483. We have about 27 different spreadsheets active. They are needed to accommodate the many different logbook formats for the various ships and years. When I saved this spreadsheet and re-opened it, I got just one white line. I suspect I might see none or more if I did this repeatedly. However, just scrolling so the buttons on the side are completely out of view and then doing a Ctrl-Home, I see all the white lines. I did the same thing with a different spreadsheet that has a much smaller image: 4222314. No white lines appeared mo matter how I was moving around, or if I was entering data. So, it seems to have a problem with the very large images. Perhaps it is just my generic video card, i don't know.

I tried with the last commit in the Windows 7.2 bibisect repository and the latest unstable, but I don't see the issue. Do you still see this with 7.4? Set to NEEDINFO. Change back to UNCONFIRMED, if the problem persists. Change to RESOLVED WORKSFORME, if the problem went away.

Yes, the white lines are still there. Version: 7.4.2.3 (x64) / LibreOffice Community Build ID: 382eef1f22670f7f4118c8c2dd222ec7ad009daf CPU threads: 2; OS: Windows 10.0 Build 19044; UI render: default; VCL: win Locale: en-CA (en_CA); UI: en-US Calc: threaded
Have downloaded the attached zip. Opened the attached file with hardware acceleration turned on, anti-aliasing turned off. When scrolling down with mouse there appears one white line. Tested with Version: 7.5.0.1 (X86_64) / LibreOffice Community Build ID: 77cd3d7ad4445740a0c6cf977992dafd8ebad8df CPU threads: 6; OS: Linux 5.3; UI render: default; VCL: kf5 (cairo+xcb) Locale: de-DE (de_DE.UTF-8); UI: de-DE Calc: threaded also with LO 7.4.4.2 on OpenSUSE 15.3 64bit rpm Linux.
Tried a little bit more: The white line depends on the buttons at the left. When setting button Log | Events from position y = 9.7 cm to 9.6 cm the white line won't appear again.

Sorry, I wrote a comment and I thought attaching the image would go with the comment. The number of white lines varies, sometimes you get one, and sometimes you get several. The white lines always appear lined up with the top and/or bottom of the buttons. Each time I process the data for a new day, you get some different number of white lines. The only consistency is that any lines that appear line up with the buttons.
