Hello Jürgen, There is definitely some other issue. Filing a bug report is good. Perhaps throttling due to high temps, caused by maybe cooling-air-flow restrictions/dust. If you have a suitable way to check temps, do check those. regards, Mo

Hi Jürgen, Common to all of your 3 XP-12 installs is your monitor ? one 4K monitor 3840 x 2160 (as well as a second monitor 1680 x 1050 ? Monitor 0 + monitor 1 ) 0:00:00.000 I/wmgr: Monitor 0: { 0, 0, 3840, 2160 } 0:00:00.000 I/wmgr: Monitor 1: { 3840, 798, 1680, 1050 } 0:00:00.000 I/WXR: wxr cache: (window 000001788548C4D0) 960 x 540 Is it possible that your graphic & CPU settings are set too high for a 3840 x 2160 monitor? More so, for 2 monitors. !!!!! Is it true that the same graphic settings that worked fine with XP-11, may not work properly on XP-12 ? If so, try again with your default monitor resolution set to 1920 x 1080, and scale 100% (just one monitor to begin with. Then add the second monitor later, if all is well) Also try reducing your graphic and CPU sliders (initially) , then gradually slide them to the right, if all is well. I too have a 4K monitor, 3840 x 2400 However, the default monitor resolution is set to 1920 x 1200 , and scale is set to 100% (what is your scale?) 0:00:00.000 I/wmgr: Monitor 0: { 0, 0, 1920, 1200 } 0:00:00.000 I/WXR: wxr cache: (window 000001A8F2424C30) 480 x 300 Good Luck

Does EFM on or EFM off in XP-11 change the results?
