I've recently upgraded my main monitor to a 4K screen. Contour is unusably slow when maximised. Performance improves a little when making the window smaller, but is still very poor even when the window is too small to be practical.
After resizing the window, the cursor position differs between Windows and Contour, meaning supports are not added where expected.
Is there a solution to this? Is it a known issue?
I have no performance problems in 3D software such as Zbrush, Blender and Fusion, or slicers like Lychee and PrusaSlicer.

Computer specs?

Ryzen 7 5800X, 32 GB DDR4-3600 CL16, Samsung 980 Pro 1TB M.2-2280, GeForce GTX 950

The graphics card doesn't have enough power to drive contour at that resolution. Especially if your models have a high triangle count. I suggest upgrading that card with something more beefy.

I get this problem with no meshes loaded. Considering I get great performance in all other 3D apps I use, often working with triangle counts in the millions, the failure here is Contour's. The solution to such performance inefficiency shouldn't be throwing more power/money at it. Nonetheless, I don't expect you to rewrite the rendering code.
My workaround would be to use my second monitor, which is running at 1080. I would be more than happy to settle for this as a solution if it weren't for the cursor location bug. That is nothing to do with an underpowered graphics card. Please see attached photo.

What version of Contour are you running?

2.3 x64

Just tried the latest beta. Performance seems slightly improved, but the cursor bug is still present.

This happens with every file or a specific file? Because we can't replicate it here.

Seems like all files. Note the UI is unaffected, as are the direct translation tools. Real weird.
I tried to workaround by forcing Contour to open on my second monitor, but it doesn't respond to the utilities I've tried.
My solution for now is to set my smaller monitor as primary. Contour opens on there and I don't have that bug.
