Screen Tearing Fix?

[D3SOL4TE]

I don't know if this is the correct place to post this but I couldn't see a better alternative so apologies if it isn't.

Does anyone know if there is a solution to the horrendous screen tearing present in inkscape? I've linked a quick video demonstrating the issue for clarity.

Welcome to the forum!

This is a good enough place to post, I guess.  I haven't seen that with the current stable version.  I can't reproduce is on Windows 7.

Do you have any other instances of Inkscape open, when you see this?  I'm thinking it could be some resource or performance issue.  But just guessing, on Windows 10, you probably have 4 to 8 GB of RAM?  That should be sufficient, unless you have a few other huge files open.

Likely it's a display issue, but this is not really in my wheelhouse, as they say.  So we'll so what others think about it.

When you installed Inkscape, did you choose the full installation, or optimal?  Or did you do some kind of custom installation where something might be missing (compared to a full installation).

That looks like a pretty big screen.  Is it considered a high dpi or high resolution screen?  It seems like I might have heard something about this on that kind of screen....

Yes, there is (potentially). Try playing with the new parameter Edit > Preferences > Rendering > Rendering Tile Multiplier (mine is set to 64).
Here's some more info about the options (suggestion for improved tool tips):

Thank you both for your help, this appears to have resolved the issue.

Just incase you'r still interested brynn my display is a 27" at 2560x1440 so I'm not sure if it would be considered high resolution, especially given 4k displays are becoming more and more common now.

While somewhat moot now in answer to your other questions that screen capture was taken with only a single instance of inkscape open along with a single microsft edge window with 2/3 tabs open.

I have 16GB of DDR4 system memory. Default installation of inkscape, every box ticked minus translations if I remember correctly. Thanks again.

Yay What's the value you needed to set there?

64 since that's the highest value it'll accept.

Sadly while nowhere near as severe it still doesn't eliminate the issue entirely, e.g. if zoomed in closely and scrolling vertically.

If there are filters in the area you're working on (blur, or anything specific), you can still try to:

- increase the number of rendering threads (same subdialog, I think)
- reduce the quality of the filter effects (same subdialog, too)

The latter only applies to how things are displayed in Inkscape, exported files still get the best quality.

Or, if you don't need the filters/fills at all when tweaking details, play with the different view modes (no filter, outline).

Oh, wow, thanks for this! Increasing the Rending Tile Multiplier to 64 solved this (mostly) for me! It was really bad and driving me crazy before now, even on my well-equipped machine. (Core i7-6700K, GTX 1070, 16GB DDR4). There's still a little bit of tearing, but it's hardly noticeable.
