Thanks for the tips and link to that thread. I have also tried with and without that -dd_sw switch and neither seems to have resolved the bleed issue but removing it fixed my lag issue. I seem to get the bleed issue more with the more graphics intensive Kamikaze Bellum map. I have always used full screen as I cannot stand windows mode. I will post to the thread you linked.
Just so you know, there is NO SOLUTION to bleedthrough in Full Screen mode. Some people don't have the problem (and nobody has been able to figure out why), but for those who do get it? The only fix is to use windowed mode.
Edit: Actually there is one solution - use the -dd_sw switch. Unfortunately that gives you the lag issue, so it's not a true fix. For reference, Microsoft added the "bleedthrough bug" to Windows 10 back in 2017. Here's the thread where it was first reported, and we all tried everything in order to fix it.
