See > https://binary-factory.kde.org/job/Krita_Nightly_Appimage_Build/ Sure, I just tried krita-4.3.0-prealpha-9526f28-x86_64.appimage and it freezes the same as 4.2.8 for me. Yes it is a gaming mouse. But the tablet (Wacom Intuos) has the same problem so that shouldn't be the cause I assume. Just to be safe though I unplugged it and used a regular Logitech mouse but it made no difference. I tried both versions of Krita on a laptop and 4.2.8 was slower than 4.2.7, but not nearly as bad as this report, ie. not to the point of freezing up for long periods of time. This is strange because the laptop is underpowered compared to the desktop machine. However, I was able to partially recreate the problem on the laptop by increasing the maximum brush size to 2000px. Then when I scrubbed the scale values back and forth in the larger sizes (say between 1500 and 2000px), 4.2.8 was freezing for a few seconds at a time, whereas 4.2.7 was merely sluggish. Not sure why my desktop severely chokes on this, but you should be able to experience the performance decrease with the above procedure... A few others things I tried: - completely fresh preferences (under a different account so I wouldn't miss something) - disabling canvas acceleration Neither made a difference. Does the fact that it happens with canvas acceleration disabled rule out graphics drivers being the cause? The only other thing I can think of is that my desktop is an AMD cpu and the laptop is Intel. Could the brush resize code be using intel-specific instructions? In any case, thanks for looking into this. I will be happy to do any other tests you can think of. -- You are receiving this mail because: You are watching all bug changes.
