[Pharo-project] 4.1.1beta2u redraw issue
If I resize a window with the Mac 4.1.1beta2u vm, it takes a really long time to redraw, sometimes up to 2 minutes or so in time. horizontally, it does it immediately. this only impact on a resize that adds/removes space vertically.

Have you tried with a previous VM? Have you tried with a previous image? -- Damien Cassou http://damiencassou.seasidehosting.st "Lambdas are relegated to relative obscurity until Java makes them popular by not having them." James Iry

yes but not in a scientific fashion. my previous pharo stuff was rather dated by this point. where can i download more recent images and vms? i could probably pinpoint when it became an issue.
I'm curious if anyone else has seen this. There is some specialized code in the VM, years old to deal with issues around resizing windows. However in the past there has been bugs where Morphic gets confused about the drawing rules then *every* pixel draw to the Display is flushed to the VM. That generates *millions* of draw requests. To work around that we (for years) actually flush the drawing surface to the screen controller process every N milliseconds so drawing is *slow*, but not like 2 minutes. Seconds perhaps.

i've been playing with this a bit more and if i open a window or minimize one or close one while waiting for a redraw, then the redraw happens. i've loaded up a ton of images and found: last good pharo dev image: pharo0.1-10279dev09.04.3 first bad pharo dev image: pharo0.1-10284dev09.04.4 On May 26, 2009, at 10:12 PM, John M McIntosh wrote:

Thanks a lot for tracking that bug. 279 - Fix for http://code.google.com/p/pharo/issues/detail?id=726 add #sender method to BlockClosure - Add messages to BlockClosure to fix issue http://code.google.com/p/pharo/issues/detail?id=722 - Issue 746: missing package for Closure and friends - Work-around for issue http://code.google.com/p/pharo/issues/detail?id=739 We cannot run some Debugger tests profiled... ... because Debugger would reset Tally Timer class var. Work around is to put a Timer ifNotNil: protection... - fix closureParser invocation (should probably clean the rest) 280 Issue 748: literals do -> literalsDo: 281 Issue 724: BlockClosure DNU when displayed in Debugger 282 - font update at startup as a preference (fixes http://code.google.com/p/pharo/issues/detail?id=689) - Issue 749: Put back ensureEndsWith: 283 'Event part one' 284 'New event part two'. Well I imagine that event is the problem :) On May 27, 2009, at 5:49 AM, Sean Allen wrote:
